Start with the digit in the tenths place, then move to the hundredths place, and finally, to the thousandths place. The digits to the right of the decimal point represent fractions of a whole number, and the further right the digit is, the smaller the fraction will be. One strategy to help you understand is to read the number in parts before and after commas and/or decimal points.

COMPOSING AND DECOMPOSING MULTI-DIGIT NUMBERS MA.5.NSO.1.3 Compose and decompose multi-digit numbers with decimals to the thousandths in multiple ways using the values of the digits in each place. Demonstrate the compositions or decompositions using objects, drawings and expressions or equations. To compose a number, we combine the values of its individual digits in their respective places. Each digit in a multi-digit number represents a specific place value such as ones, tens, hundreds, thousandths, and so on. By adding these values together, we can create a complete number. Example: Compose the number 0.735. The digit 7 is in the tenths place, representing 7 tenths (0.7). The digit 3 is in the hundredths place, representing 3 hundredths (0.03). Finally, the digit 5 is in the thousandths place, representing 5 thousandths (0.005). HUNDREDS

By adding these values together, we compose the number 0.735.

Each digit represents a specific place value, such as ones, tens, hundreds, thousandths, and so on. Understanding the value of each digit in its respective place is essential to effectively decompose numbers. Example: When decomposing the number 3.725, we can identify the value of each digit in terms of its place value. The digit 3 represents three whole units (3), the digit 7 represents seven tenths (0.7), the digit 2 represents two hundredths (0.02), and the digit 5 represents five thousandths (0.005). HUNDREDS

PLOTTING AND ORDERING MULTI-DIGIT NUMBERS

MA.5.NSO.1.4 Plot, order and compare multi-digit numbers with decimals up to the thousandths.

Use plotting techniques on a number line to order and compare multi-digit numbers. Start by selecting an appropriate scale for the number line or coordinate plane, placing the whole number part of the decimal in its corresponding position. Then, determine the location of the decimal part by dividing the remaining space between whole numbers into equal intervals based on the place value of the decimal. Example: Plot the number 625.75 on a number line. To plot the number 625.75 on a number line, determine the whole numbers that come before and after the number. Place those two numbers on opposite sides of the number line. First 625

626

Next, find the midpoint between the numbers. Plot the number in the middle of the number line. Second

625.00

625.50

626.00

Then, find the midpoints between these numbers. Plot the numbers on the number line. In this instance, the number 625.75 can be found between 625.5 and 626. Third 625.00

625.25

625.50

625.75

626.00

In addition to using place value to compare the values of digits in each place, you can also use the number line. The number line is a visual representation of numbers that can help you compare their values. To use the number line to compare two numbers, plot them on the line, then look at their relative positions. The number to the right is always greater than the number to the left. Example: To compare 625.75 to 625.67, first plot both points on a line using units that are close to the numbers being compared. Next, locate each point on the line and determine which is farther to the right. First 625.75

625.65

625.85

Second

625.65

625.75

625.70

625.80

625.85

625.8

625.85

Third 625.65

625.66

625.67

625.68

625.69

625.70

625.71

625.72

625.73

625.74

625.75

In this case, 625.75 is farther to the right than 625.67, so it is greater. 25

ROUNDING MULTI-DIGIT NUMBERS MA.5.NSO.1.5 Round multi-digit numbers with decimals to the thousandths to the nearest hundredth, tenth or whole number. Use place values to round decimals to any place. Example: Round 49.253 to the nearest tenths: 4 9 . 2 5 3 STEP 1: Underline the targeted digit to be rounded. STEP 2: Look at the number to the right of the underlined digit. If that number is 0 - 4, then the underlined digit stays the same. If the number is 5 - 9, then the underlined digit must be increased by 1. STEP 3: Change all the digits to the right of the targeted digit to zero. The rounded number becomes: 4 9 . 3 0 0 or 4 9 . 3

Use a number line to round decimals to any place. Example: Round 49.253 to the nearest tenths: 4 9 . 2 5 3 STEP 1: Underline the targeted digit to be rounded. STEP 2: Draw a number line with intervals at the far right and left sides of the line.

STEP 3: Keep the targeted digit the same. Change all of the digits to the right to zeros. The new number will be (49.200). Place this number on the far left side of the number line. 49.200

STEP 4: Increase the targeted digit by 1 number and change all the digits to the right of the targeted digit to zeros. 49.200

49.300

STEP 5: Add intervals to allow numbers in increasing order to be placed from 49.200 to 49.300 on the number line. Place a dot on the number line that represents the number to be rounded. Determine whether that number is closer to 49.200 or 49.300. 49.200

49.250

49.300

The number is closest to 4 9 . 3 0 0. Therefore, the number rounded to the nearest tenth is 49.3. 33

MULTIPLYING MULTI-DIGIT WHOLE NUMBERS

MA.5.NSO.2.1 Multiply multi-digit whole numbers including using a standard algorithm with procedural fluency.

Use the standard algorithm to multiply multi-digit whole numbers.

STEP 1: Write the two numbers vertically, lining up the digits based on their place values (ones, tens, hundreds, etc.) STEP 2: Start with the rightmost digit of the second number (the one in the ones place) and multiply it by each digit in the first number, one by one. STEP 3: Write the products below each digit in the first number, aligning them based on their place values. STEP 4: Once you have multiplied the rightmost digit of the second number by all the digits in the first number, move to the next digit of the second number (the one in the tens place) and repeat the multiplication process with the digits in the first number. STEP 5: Continue this process for each digit in the second number, moving from right to left, until you have multiplied each digit by all the digits in the first number. STEP 6: After multiplying all the digits, add up the partial products, starting from the rightmost column, to obtain the final product. STEP 7: Carry over any values that exceed 9 to the next column when adding up the partial products. STEP 8: Write the final product below the line and ensure that the digits are aligned based on their place values.

NOTE: Always double-check your work and perform any necessary regrouping or adjustments to ensure accuracy.

DIVIDING MULTI-DIGIT WHOLE NUMBERS MA.5.NSO.2.2 Divide multi-digit whole numbers, up to five digits by two digits, including using a standard algorithm with procedural fluency. Represent remainders as fractions. Use the standard algorithm to divide multi-digit whole numbers.

STEP 1: Write the dividend (the number being divided) inside the division symbol and the divisor (the number doing the dividing) outside the division symbol. Make sure the digits are lined up based on their place values. STEP 2: Begin dividing by the leftmost digit of the divisor. If the divisor does not evenly divide into the first digit of the dividend, carry over the remaining value to the next digit. STEP 3: Divide the carried-over value along with the next digit of the dividend by the divisor. Continue this process until you have divided all the digits of the dividend. STEP 4: Write the quotient (the result of each division step) above the division symbol, aligning the digits based on their place values. STEP 5: Multiply the quotient by the divisor and subtract the result from the corresponding digits of the dividend. Write the difference below the line. STEP 6: Bring down the next digit from the dividend, and continue the process of dividing and subtracting until you have gone through all the digits of the dividend. STEP 7: If there are digits remaining in the dividend after the division process, add a decimal point and zeros as necessary to the quotient and continue dividing.

STEP 8: If there is a remainder after all the divisions, represent it as a fraction. Write the remainder as the numerator and the divisor as the denominator. Simplify the fraction if possible.

ADDING AND SUBTRACTING MULTI-DIGIT NUMBERS MA.5.NSO.2.3 Add and subtract multi-digit numbers with decimals to the thousandths, including using a standard algorithm with procedural fluency. Use a place value chart to add and subtract decimals. Example: 5.73 + 1.2 = ? STEP 1: Align the numbers vertically, making sure the decimal points are directly above each other. Use zeros to make sure all the numbers to be added have the same number of digits. STEP 2: Starting from the rightmost column (the hundredths place), perform the appropriate operation (addition or subtraction) for the digits in that column. If adding, add the digits together, considering any carried-over digits from the previous column. If subtracting, subtract the digits, considering any borrowed digits from the previous column. STEP 3: Move to the next column (tenths place) and perform the appropriate operation for the digits in that column, including any carried-over or borrowed digits from the previous step. If adding, add the digits together, considering any carried-over digits. If subtracting, subtract the digits, considering any borrowed digits. STEP 4: Repeat this process for each subsequent column, moving from right to left (ones place, etc.), performing the appropriate operation (addition or subtraction) for the digits in each column and carrying over or borrowing as necessary. STEP 5: Once you have completed the operations for all columns, write the final result below the line. STEP 6: If there are any carried-over or borrowed digits at the leftmost column, write them as well. STEP 7: Place the decimal point in the result directly below the decimal points in the numbers being added or subtracted.

NOTE: Check your work by performing the operations column-wise from right to left. The result should match the original calculation.

MULTIPLYING & DIVIDING MULTI-DIGIT NUMBERS WITH DECIMALS MA.5.NSO.2.5 Multiply and divide a multi-digit number with decimals to the tenths by one-tenth and one-hundredth with procedural reliability. MA.5.NSO.2.4 Explore the multiplication and division of multi-digit numbers with decimals to the hundredths using estimation, rounding and place value. Estimate the product by rounding. Example: 3.25 × 1.75 = ? STEP 1: Estimate the product by rounding each decimal number to a whole number. This simplifies the calculation. (e.g., 3.25 ≈ 3 and 1.75 ≈ 2) STEP 2: Multiply the rounded whole numbers together using the standard multiplication algorithm (e.g., 3 × 2 = 6) STEP 3: Count the total number of decimal places in the original numbers being multiplied.

STEP 4: Place the decimal point in the product so the number of decimal places matches the count from step 3. Start from the rightmost digit (e.g., 3.25 × 1.75 ≈ 6). STEP 5: Adjust the decimal point position based on the level of estimation used in step 1. This step is optional but can improve the accuracy of the result.

Estimate the quotient by rounding. Example: 5.68 ÷ 2.34 = ? STEP 1: Estimate the quotient by rounding the dividend and divisor to the nearest whole numbers. This simplifies the calculation (e.g., 5.68 ≈ 6 and 2.34 ≈ 2). STEP 2: Divide the rounded dividend by the rounded divisor using the standard division algorithm (e.g., 6 ÷ 2 = 3). STEP 3: Count the total number of decimal places in the original dividend and divisor. STEP 4: Place the decimal point in the quotient so the number of decimal places matches the count from step 3. Start from the rightmost digit (e.g., 5.68 ÷ 2.34 ≈ 3). STEP 5: Adjust the decimal point position based on the level of estimation used in step 1.

DIVIDING TWO WHOLE NUMBERS AS A FRACTION

MA.5.FR.1.1 Given a mathematical or real-world problem, represent the division of two whole numbers as a fraction.

When representing a real-world-problem as division, place the dividend over the divisor. STEP 1: Identify the two whole numbers involved in the problem. The dividend is the number being divided, and the divisor is the number dividing the dividend. STEP 2: Write the dividend as the numerator of the fraction. STEP 3: Write the divisor as the denominator of the fraction. STEP 4: Simplify the fraction, if possible, by finding the greatest common divisor (GCD) of the numerator and denominator and dividing both by it. This step is optional but can be done to express the fraction in its simplest form.

STEP 5: If the resulting fraction is an improper fraction (the numerator is greater than or equal to the denominator), convert it to a mixed number (a whole number with a fraction part).

Determining the dividend and the divisor in a real-world problem depends on the context and the specific details provided.

STEP 1: Look for words like "divide," "split," or "share." These words mean the problem is about dividing a number into parts. STEP 2: Check the sentence structure and order of the numbers. The dividend is the number being divided, while the divisor tells how many parts the dividend is split into. STEP 3: Think about what is happening in the problem and decide which number is the total and which is the size of each part. STEP 4: Identify what you know and do not know. If the problem gives you information on one quantity and asks for the other, the known quantity is usually the dividend, and the unknown quantity is the divisor.

ADDING & SUBTRACTING FRACTIONS WITH UNLIKE DENOMINATORS

MA.5.FR.2.1 Add and subtract fractions with unlike denominators, including mixed numbers and fractions greater than 1, with procedural reliability. Add and subtract fractions with unlike denominators by replacing the fractions with equivalent fractions with like denominators.

Example: 2 + 5 = ?

3

4

STEP 1: Identify the denominators of the fractions you are working with. Denominators are the bottom numbers of the fractions that represent the total number of equal parts in a whole. STEP 2: Determine the least common multiple (LCM) of the denominators. The LCM is the smallest multiple that is divisible by both denominators. This will be your common denominator for the fractions.

STEP 3: Convert each fraction to an equivalent fraction with the common denominator. Multiply the numerator and denominator of each fraction by the same factor that will make the denominator equal to the LCM. STEP 4: Perform the desired operation (addition or subtraction) on the numerators of the fractions. For addition, add the numerators together. For subtraction, subtract the second numerator from the first numerator. STEP 5: Keep the common denominator unchanged. STEP 6: If the resulting fraction is an improper fraction, simplify it by reducing it to its simplest form, if necessary. Find the greatest common divisor (GCD) of the numerator and denominator, and divide both by the GCD.

MULTIPLYING FRACTIONS BY FRACTIONS MA.5.FR.2.2 Extend previous understanding of multiplication to multiply a fraction by a fraction, including mixed numbers and fractions greater than 1, with procedural reliability. Multiplication to multiply a fraction by a fraction often requires converting mixed numbers to improper fractions.

Example: 2 1 ×

4

1 4 = ? 5

STEP 1: If you have mixed numbers, convert them to improper fractions. Multiply the whole number by the denominator, then add the numerator. The result becomes the new numerator, and the denominator remains the same. STEP 2: Simplify the fractions before multiplying to make calculations easier. Divide the numerator and denominator by their greatest common divisor.

STEP 3: Multiply the numerators of the fractions together to get the new numerator, and multiply the denominators together to get the new denominator. STEP 4: If possible, simplify the resulting fraction by dividing the numerator and denominator by their greatest common divisor. STEP 5: When multiplying a fraction greater than 1 by another fraction, follow the same steps. The resulting product will be greater than the original fractions. STEP 6: When dealing with mixed numbers, first convert them to improper fractions (Step 2). Then follow the same steps for multiplying fractions. Remember to simplify if needed.

Example:

2 1 × 1 4 = ? 4

5

2 1 = 9 4

PREDICTING THE RELATIVE SIZE OF THE PRODUCT MA.5.FR.2.3 When multiplying a given number by a fraction less than 1 or a fraction greater than 1, predict and explain the relative size of the product to the given number without calculating.

Make predictions about the relative size of the product without actually performing the multiplication.

STEP 1: Determine if the fraction is less than 1 or greater than 1. If the fraction is less than 1, the numerator is smaller than the denominator. For example, 1/2 or 3/4. If the fraction is greater than 1, the numerator is larger than the denominator. For example, 3/2 or 5/4.

STEP 2: Consider the effect of multiplying by a fraction less than 1. When you multiply a given number by a fraction less than 1, the product will be smaller than the given number. This is because you are taking a part of the given number, which is less than the whole.

Example:

STEP 3: Consider the effect of multiplying by a fraction greater than 1. When you multiply a given number by a fraction greater than 1, the product will be larger than the given number. This is because you are taking more than the whole, as the numerator of the fraction is larger than the denominator.

DIVIDING UNIT FRACTIONS BY WHOLE NUMBERS MA.5.FR.2.4 Extend previous understanding of division to explore the division of a unit fraction by a whole number and a whole number by a unit fraction.

Divide unit fractions by a whole number by multiplying its reciprocal.

STEP 1: Understand that a unit fraction is a fraction with a numerator of 1 (e.g., 1/2, 1/3, and 1/4). STEP 2: When dividing, express the whole number as a fraction with a denominator of 1. For example, if you want to divide 1/3 by 2, rewrite 2 as 2/1. STEP 3: Take the reciprocal of the whole number (flip it). For example, 1/3 ÷ 2/1 = 1/3 ÷ 1/2. STEP 4: Next, change the division sign to multiplication and multiply the unit fraction by the reciprocal of the whole number. For example, 1/3 × 1/2 = 1/6.

1 ÷ 2 = ? 3 1 × 1 = ? 3 2 1 × 1 = 1 3 6 2 Divide a whole number by a unit fractions by multiplying its reciprocal.

STEP 1: Express the whole number as a fraction with a denominator of 1 (e.g., 6 = 6/1). STEP 2: When dividing a whole number by a unit fraction, take the reciprocal (flip) of the unit fraction. For example, if you want to divide 6/1 by 1/2, rewrite 1/2 as 2/1. STEP 3: Change the division sign to multiplication and multiply the whole number by the reciprocal of the unit fraction. For example, 6/1 × 2/1 = 12/1.

SOLVE MULTI-STEP REAL-WORLD PROBLEMS MA.5.AR.1.1 Solve multi-step real-world problems involving any combination of the four operations with whole numbers, including problems in which remainders must be interpreted within the context. Use a bar model to visually represent the quantities and relationships described when solving multi-step real-world problems.

STEP 1: Carefully read the real-word problem. Identify the keywords which indicate what needs to be solved and the operations to be used. STEP 2: Some common keywords used in multi-step word problems are as follows: ADDITION: in all, sum, altogether, combined, plus, increased by, more than, added to, totaled SUBTRACTION: less, fewer, left, minus, difference, take away, deduct, remaining, decreased by MULTIPLICATION: product, times, of, multiplied by, twice, double, triple, each*, per* DIVISION: quotient, divide, half, split, share, evenly, equal groups, each*, per*

* Keywords for either multiplication or division. Students must use other keywords to determine which of the two operations is required. STEP 3: Identify the known quantities using bars (rectangles) that are proportional to the values you wish to represent. Be sure to include the units of measurement. STEP 4: Continue manipulating the bars to represent each operation until the problem is solved. STEP 5: Verify the answer using the bar model you created. Example: Sarah baked 3 trays of cookies. Each tray had 24 cookies. If she gave half of the cookies to her friends, how many cookies did she have left? 72 cookies

SOLVE REAL-WORLD PROBLEMS INVOLVING FRACTIONS MA.5.AR.1.2 Solve real-world problems involving the addition, subtraction, or multiplication of fractions, including mixed numbers and fractions greater than1. When solving real-world problems involving fractions, including mixed numbers and fractions greater than 1, first identify what needs to be solved and what operations (addition, subtraction, or multiplication) need to be carried out.

STEP 1: Carefully read the real-word problem. Identify the keywords which indicate what needs to be solved and the operations to be used. Some common keywords used in multi-step word problems are as follows: ADDITION: in all, sum, altogether, combined, plus, increased by, more than, added to, totaled SUBTRACTION: less, fewer, left, minus, difference, take away, deduct, remaining, decreased by MULTIPLICATION: product, times, of, multiplied by, twice, double, triple, each*, per* DIVISION: quotient, divide, half, split, share, evenly, equal groups, each*, per*

* Keywords for either multiplication or division. Therefore, students must use other keywords to determine which of the two operations is required. STEP 2: Convert mixed numbers to improper fractions where needed. Find the least common denominator (LCM) for all fractions in the problem with different denominators. STEP 3: If the problem involves addition or subtraction, use the common denominator to add or subtract the fractions. Add or subtract the numerators, keep the common denominator, and simplify if possible. STEP 4: If the problem involves multiplication, multiply the numerators together to get the new numerator. Multiply the denominators together to get the new denominator. STEP 5: Simplify the resulting fraction by dividing the numerator and the denominator by the greatest common factor (GCF). STEP 6: Convert the answer to a mixed number by dividing the numerator by the denominator. The quotient will be the whole number, and the remainder will be the numerator of the fraction. Write the mixed number in the form of a whole number and a proper fraction.

TRUE OR FALSE EQUATIONS & DETERMINING THE UNKNOWN

MA.5.AR.2.3 Determine and explain whether an equation involving any of the four operations is true or false.

Use the order of operations (PEMDAS) when evaluating multi-step numerical expressions.

STEP 1: Use the order of operations (PEMDAS) to simplify each side of the equation, one side at a time. STEP 2: Perform any calculations within parentheses first, followed by exponents, multiplication and division (from left to right), and finally addition and subtraction (from left to right). STEP 3: After simplifying and solving each side of the equation, compare the values obtained on both sides. STEP 4: If the equation is true, explain that the values on both sides are equal, and the equation holds. If the equation is false, explain that the values on both sides are not equal, and the equation does not hold.

PEMDAS is a mnemonic device used to remember the order of operations in arithmetic: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right). The phrase "Please Excuse My Dear Aunt Sally" is often used as an analogy to help remember the order of operations.

WRITING EQUATIONS TO DETERMINE THE UNKNOWN MA.5.AR.2.4 Given a mathematical or real-world context, write an equation involving any of the four operations to determine the unknown whole number with the unknown in any position. Use this set of steps to solve mathematical or real-world context involving an unknown number.

STEP 1: Find the unknown number in the problem. STEP 2: Assign a letter to represent the unknown number. STEP 3: Write an equation using +, -, ×, or ÷ with the letter you chose in Step 2 to represent the unknown number. STEP 4: Solve the equation to find the value of the unknown number. STEP 5: Check your answer by putting the value you found in step 4 back into the original equation.

Example: Cassandra has twice as many tokens as Kyle. Together, they have 75 tokens. How many tokens does Kyle have? First, identify the unknown by using the first letter of Kyle’s name "K" to represent the number of tokens Kyle has. Next, translate the information given into an equation. Since Cassandra has twice as many tokens as Kyle, it can be expressed as: Cassandra 's tokens = 2 × Kyle’s tokens Together, they have 75 tokens, so we can write the equation: Cassandra 's tokens + Kyle’s tokens = 75 Substituting the expressions from above: 2K + K = 75 Continue by simplifying and solving the equation. Combine like terms: 2K + 1K = 75 3K = 75 Next, divide both sides by 3 to isolate the variable “K” to one side. K = 25

RULES FOR DESCRIBING PATTERNS AS AN EXPRESSION MA.5.AR.3.1 Given a numerical pattern, identify and write a rule that can describe the pattern as an expression.

To find a pattern in a series of numbers, look for a consistent difference or ratio between each number. STEP 1: Study the given pattern of numbers. For example, 2, 4, 6, 8, 10. STEP 2: Figure out how the numbers in the pattern are related. Check for a consistent difference or ratio between each number. STEP 3: If the pattern has a consistent difference between each number (arithmetic sequence), subtract any number from the one before it to find the common difference. In our example, the common difference is 2 because each number is 2 more than the previous one. STEP 4: If the series has a consistent ratio between each number (geometric sequence), divide any number by the one before it to find the common ratio. In our example, the common ratio is 2 because each number is twice the previous one.

STEP 5: Write a formula using variables to represent the pattern. For an arithmetic sequence, the formula will include the common difference (d) and the first term (a). For a geometric sequence, the formula will include the common ratio (r) and the first term (a). STEP 6: For our example pattern (2, 4, 6, 8, 10), since it has a common difference of 2, we can write the formula as n = 2n, where “n” represents the nth term of the sequence. STEP 7: If needed, simplify the formula or adjust it to fit the specific starting term or index of the pattern. For example, if the pattern starts with the term “a1” instead of “a0”, you may need to adjust the expression accordingly. STEP 8: Check the formula by applying it to additional terms in the pattern to see if it correctly predicts the values. For our example, when we substitute “n” with 1, 2, 3, 4, and 5 in the formula (n) = 2n, we get the correct corresponding values of 2, 4, 6, 8, and 10, respectively. +3

RECORDING INPUTS AND OUTPUTS ON A TWO-COLUMN TABLE

MA.5.AR.3.2 Given a rule for a numerical pattern, use a two-column table to record the inputs and outputs.

Use a two-column table to record inputs and outputs for a given rule in a numerical pattern.

STEP 1: Study the pattern and its rule. For example, if the rule is "multiply each input by 2," it means that each input will be doubled to produce the corresponding output. STEP 2: Create a two-column table with one column labeled "Input" and the other labeled "Output." STEP 3: Add the initial input as the starting value on the input column. This can be any number, depending on the given rule and pattern. For example, if the pattern starts with 2, you can choose 2 as the first input. STEP 4: Apply the given rule to the initial input to determine the corresponding output. Write the input value in the "Input" column and the calculated output value in the "Output" column. STEP 5: Continue the pattern by using the output value from the previous step as the next input. Apply the rule to this new input to calculate the next output. Write these values in the appropriate columns of the table. STEP 6: Repeat the process until all of the inputs and outputs are added in to clearly see the pattern.

The relationship between the input and the output is 3x+ 2. If the 1 is plugged into the equation, “3x+ 2”, we learn that “5 is the result. If the 2 is plugged into the equation, “3x+ 2”, we learn that “8 is the result. If the 3 is plugged into the equation, “3x+ 2”, we learn that “11 is the result. etc... 177

REAL-WORLD PROBLEMS INVOLVING MONEY

MA.5.M.2.1 Solve multi-step real-world problems involving money using decimal notation.

Use decimal notation to solve multi-step real-world problems involving money. STEP 1: Identify the prices, quantities, discounts, or any other monetary values mentioned in the problem. Record the decimal notation for each value. STEP 2: Determine the unknown values that need to be solved, along with any comparisons that must be made. STEP 3: Perform the necessary operations to find the answer. Example 1 John is at the supermarket and wants to buy orange juice. The first option offers a 32-ounce bottle for $2.99, while the second offer is a 16-ounce bottle for $1.50. Which option is cheaper per ounce? $2.99 ÷ 32 ounces = $0.09 per ounce

and

$1.65 ÷ 16 ounces = $0.10 per ounce

$0.09 per ounce < $0.10 per ounce Therefore, $2.99 for 32 ounces of orange juice is a better buy. Example 2 Alice, Bob, and Carol decided to contribute money to buy a gift for their friend. Bob contributed $5 more than twice the amount contributed by Alice, and Carol contributed $4 less than the amount contributed by Bob. If the price of the gift was $41, how much did Carol contribute? B = Bob, A = Alice, and C = Carol B = $5 + 2A

(Bob contributed $5 more than twice the amount contributed by Alice)

C = B - $4

(Carol contributed $4 less than the amount contributed by Bob)

If the price of the gift was $41, how much did Carol contribute?

$41 = A

B

C

$41 = 1A + $5 + 2A + $5 + 2A - $4 $41 = 5A + $6 $41 - $6 = 5A + $6 - $6 193

$35 = 5A

B = $5 + 2A

C = B - $4

$35 = 5A 5 5

B = $5 + 2 × $7

C = $19 - $4

B = $5 + $14

C = $15

$7 = A

B = $19

FINDING THE PERIMETER AND AREA OF A RECTANGLE MA.5.GR.2.1 Find the perimeter and area of a rectangle with fractional or decimal side lengths using visual models and formulas.

Perimeter is defined as the total distance around the edge of the figure. To calculate the perimeter:

Perimeter = 2

+2w

Step 1: Identify the length of the rectangle and understand that it represents the opposite side as well. Step 2: Identify the width of the rectangle and understand that it represents the opposite side as well. Step 3: Add the length of each side to find the perimeter of the rectangle. Use your knowledge of adding fractions and decimals to complete this calculation.

1 + 3 1 + 6 1 + 3 1 = 19 2 Example 1: Perimeter = 6.2 + 3.5 + 6.2 + 3.5 = 19.4 Example 2: Perimeter = 6 5

USING VOLUME AS AN ATTRIBUTE OF THREE-DIMENSIONAL FIGURES MA.5.GR.3.1 Explore volume as an attribute of three-dimensional figures by packing them with unit cubes without gaps. Find the volume of a right rectangular prism with whole-number side lengths by counting unit cubes.

Count the number of unit cubes to determine the volume. Key:

Count the unit cubes for the length, width, and height of a rectangular prism to find its volume.

Step 1: Determine the length, width, and height of the right rectangular prism. These dimensions should be whole numbers.

Step 2: Multiply the number of unit cubes in the base layer (length × width) by the number of layers (height) to find the total number of unit cubes inside the prism. This total count represents the volume of the right rectangular prism in terms of unit cubes. Step 3: Volume = Length × Width × Height

FINDING THE VOLUME OF A RIGHT RECTANGULAR PRISM

MA.5.GR.3.2 Find the volume of a right rectangular prism with whole-number side lengths using a visual model and a formula.

Calculate the volume of a rectangular solid using the formula: V = length × width × height. To find the volume of a right rectangular prism with whole-number side lengths, you can use both a visual model and a formula. The volume of a rectangular prism can be calculated using the formula: Volume = length × width × height or l × w × h.

STEP 1: Copy the formula for volume (Volume = length × width × height). STEP 2: Plug in the measurements for length, width, and height found on the rectangular prism into the equation.

STEP 3: Multiply the length, width, and height together, ensuring that you are performing the multiplication correctly.

STEP 4: The result you get after performing the multiplication is the volume of the right rectangular prism.

STEP 5: Make sure to include the correct units for volume (e.g., cubic units).

PLOTTING POINTS REPRESENTATIVE OF REAL-WORLD PROBLEMS MA.5.GR.4.2 Represent mathematical and real-world problems by plotting points in the first quadrant of the coordinate plane and interpret coordinate values of points in the context of the situation. Interpreting the coordinate values can effectively represent mathematical and real-world problems.

STEP 1: Read the real-world problem, and identify the relevant variables and quantities involved. STEP 2: Understand what each coordinate represents, such as a measurement of time, distance, height, length, etc. STEP 3: Assign appropriate coordinates to the quantities, with the x-coordinate representing the first quantity (time, number of items, etc.) and the y-coordinate (distance, cost, etc.) representing the second value. STEP 4: Plot the points in the first quadrant of the coordinate plane based on the assigned coordinates for each situation. STEP 5: Read the coordinates (x, y) of each plotted point and interpret them in the context of the problem.

CREATING TABLES, GRAPHS, AND LINE PLOTS

MA.5.DP.1.1 Collect and represent numerical data, including fractional and decimal values, using tables, line graphs or line plots. Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8). STEP 1: Determine the range of your data, which is the minimum and maximum values of your measurements. This will help you set up the axis appropriately. STEP 2: Create a horizontal axis (x-axis) for your line plot. Label it with the fractions you are working with, such as 1/8, 1/4, 3/8, 1/2, and so on. STEP 3: Divide the x-axis into equal segments based on the fractions you are dealing with. For example, if you are using 1/5, each segment would represent 1/5 of the unit. STEP 4: Give your line plot a descriptive title that explains what the plot is displaying, such as "Measurements in Fractions of a Unit." STEP 5: Title the x-axis with a clear label like "Fractions" or "Measurement Units." Add a label to the y-axis if your measurements have corresponding values on another scale. Example:

MEAN, MEDIAN, MODE, AND RANGE MA.5.DP.1.2 Interpret numerical data, with whole-number values, represented with tables or line plots by determining the mean, mode, median or range. Calculating the mean (average) of a set of whole-number values. STEP 1: Add up all of the values provided in the table or line plot.

Example:

23

FIRST: 5 + 7 + 12 + 12 + + 15 + 16 + 20 + 22 + 23 + 28 = 160 SECOND: 160 / 10 = 16 THIRD: Interpret the result as “the mean number of tickets sold over 10 hours is 16”.

Calculate the median (middle number of an ordered data set) STEP 1: Arrange the data in ascending order. STEP 2: If the data set has an odd number of values, the median is the middle value. Example: FIRST: 5, 7, 12, 12, 15, 16, 18, 20, 22, 23, 28

THIRD: 34 ÷ 2 = 17

SECOND: 16 + 18 = 34 (two numbers in the middle)

FOURTH: Interpret the result as the median is 17.

Calculate the mode (the number that appears most frequently).

Calculate the range (the number that appears most frequently).

STEP 1: Identify the value that occurs with the highest frequency.

STEP 1: The range is the difference between the highest and lowest values in the data set.

STEP 2: If multiple values share the highest frequency, the data set is multimodal, and there is no mode.

STEP 2: Subtract the smallest value from the largest value to find the range.

Example:

Example:

273

FIRST: 5, 7, 12, 12, 15, 16, 18, 20, 22, 23, 28

FIRST: Identify the highest value: 28

SECOND: 12 appears twice whereas, all other numbers appear only once.

SECOND: Identify the lowest value: 5 THIRD: Subtract 28 - 5 = 23
