COMPOSING AND DECOMPOSING FOUR-DIGIT NUMBERS
MA.3.NSO.1.2 Compose and decompose four-digit numbers in multiple ways using thousands, hundreds, tens and ones. Demonstrate each composition or decomposition using objects, drawings and expressions or equations. Use a place value table to compose a four-digit number and combine each digit’s values in their respective place values. Each digit in a multi-digit number, starting from the rightmost digit and moving left, represents ones, tens, hundreds, and thousandths. By adding these values together, you can create a complete number. Example: Compose a number that has 5 thousands, 62 tens, and 4 ones. THOUSANDS

Regrouping: •
10 ones = 1 ten
•
10 tens = 1 hundred
5,000 + 620 + 4 = 5,624 Adding the value of each digit, we can compose the number as: 5,000 + 620 + 4 = 5,624
When decomposing a four-digit number, remember that each digit represents a specific place value. Starting from the rightmost digit and moving left, each digit represents ones, tens, hundreds, and thousandths. You can also regroup each digit to represent different place values. Example: Decompose the number 8,736. The number 8,736 can be interpreted as having 8 thousands, 7 hundred, 3 tens, and 6 ones. THOUSANDS

PLOTTING AND ORDERING WHOLE NUMBERS MA.3.NSO.1.3 Plot, order and compare whole numbers up to 10,000. To plot, order, and compare multi-digit numbers, use a number line with an appropriate scale. If the numbers are too close in value, use a smaller interval in scale. If the numbers are too far apart in value, use a bigger interval in scale. Ensure that the smallest number on the number line is smaller than the least number and that the largest number on the number line is greater than the greatest number. Remember, the number to the right is always greater than the number to the left.
Example: Plot 3,544, 3,872, and 3,250 on a number line and order the numbers from least to greatest. The numbers are too far apart (difference of hundreds), so using 100s as intervals is best. Also, the least number is 3,250, so use 3,200 as the smallest number on the number line. The greatest number is 3,872, so use 3,900 as the largest number on the number line. 3,200
3,300
3,400
3,500
3,600
3,700
3,800
3,900
Plot the numbers: 3,250 is 1 between 3,200 and 3,300, 3,544 is about less than halfway 4 3 between 3,500 and 3,600, and 3,872 is about 4 between 3,800 and 3,900. 3,250 3,200
3,544 3,300
3,400
3,500
3,872 3,600
3,700
3,800
3,900
Therefore, 3,544 is greater than 3,250, and 3,872 is greater than 3,544. A place value table can be used to compare and order multi-digit numbers. Begin by comparing the digits, starting with the leftmost digit and moving to the right.
Example: Order the numbers 3,544, 3,872, and 3,250 from least to greatest. THOUSANDS HUNDREDS

The three numbers have the same thousands digit. So, compare the hundreds digits. Since 8 > 5 > 2, then it means 3,872 is greater than 3,544, and 3,544 is greater than 3,250.
Therefore, 3,250 < 3,544 < 3,872. 17

ROUNDING WHOLE NUMBERS MA.3.NSO.1.4 Round whole numbers from 0 to 1,000 to the nearest 10 or 100. Use a number line to round numbers to the nearest 10. Use benchmark tens as endpoints of the number line, and plot the number needed to be rounded off. Check which benchmark ten the number is closer to.
Example: Round 356 to the nearest 10. The number 356 falls between the benchmark tens 350 and 360, so use these numbers as endpoints of the number line. 350

Since 356 is closer to 360 (it is 4 units away from 360 and 6 units away from 350), 356 rounded to the nearest 10 is 360. Use a number line to round numbers to the nearest 100. Use benchmark hundreds as endpoints of the number line, and plot the number needed to be rounded off. Check which benchmark hundreds the number is closer to.
Example: Round 356 to the nearest 100. The number 356 falls between the benchmark hundreds 300 and 400, so use these numbers as endpoints of the number line. 300

APPLYING THE PROPERTIES OF MULTIPLICATION MA.3.AR.1.1 Apply the distributive property to multiply a one-digit number and two-digit number. Apply properties of multiplication to find a product of one-digit whole numbers. The associative property states that it does not matter how we group the numbers.
(2 × 4) × 3
The commutative property states that you can swap numbers and still get the same answer.
2 × (4 × 3)
3×4
4×3
Use rectangular arrays to demonstrate the distributive property to find the product of a one-digit number and a two-digit number.
Example: Apply the distributive property using rectangular arrays to find the product of 4 × 12. 12 can be broken down as 10 + 2.
12
Therefore, you can write 4 × 12 as 4 × (10 + 2) = (4 × 10) + (4 × 2).
4
4 × 10 = 40 4×2=8
10
2
Therefore, 4 × 12 = 40 + 8 = 48.
Use base-ten blocks to demonstrate the distributive property to find the product of a one-digit number and a two-digit number.
Example: Apply the distributive property using base-ten blocks to find the product of 4 × 12. 12 consists of 1 tens and 2 ones
4 × 12 = 4 × (10 + 2) So, 4 × 12 consists of 4 × 1 tens and 4 × 2 ones.

IDENTIFYING EVEN AND ODD WHOLE NUMBERS MA.3.AR.3.1 Determine and explain whether a whole number from 1 to 1,000 is even or odd. Use base-ten blocks to determine whether a number is even or odd. Remember that even numbers can be paired or divided into equal groups of 2 with no leftovers, while odd numbers will always have one left over when paired or divided into equal groups of 2. A block of 10 or a block of 100 can always be divided into equal groups of 2. Therefore, you only have to check the ones blocks.

VISUAL REPRESENTATION
EVEN OR ODD?
76
Based on the base-ten model, the ones blocks can be paired. So, 76 is even.
127
Based on the base-ten model, the ones blocks cannot be paired. So, 127 is odd.
219
Based on the base-ten model, the ones blocks cannot be paired. So, 219 is odd.
94
Based on the base-ten model, the ones blocks can be paired. So, 94 is even.
Use a place value table to identify if a number is even or odd by looking at the digits in the ones place. If the digit in the ones place is a multiple of 2 (0, 2, 4, 6, or 8), then the number is even. If it is not, then the number is odd.

TELLING AND WRITING TIME TO THE NEAREST MINUTE
MA.3.M.2.1 Using analog and digital clocks, tell and write time to the nearest minute using a.m. and p.m. Analog clocks are clocks that use hands to show hours and minutes. The short hand of the clock tells the hours, and the long hand of the clock tells the minutes.
Each number on an analog clock represents an interval of 5 minutes. So, 1 represents 5 minutes, 2 represents 10 minutes, 3 represents 15 minutes, etc.
Using both the short and long hands of an analog clock tells the time.
The short hand is pointing between 10 and 11, so the hours is 10. The long hand is pointing at 5, so the minutes is 25. Therefore, the time is 10:25.
Digital clocks use digital counters to tell time.
In the display of a digital clock, time is usually written in hours and minutes, separated by a colon. The first two digits tell the hours, and the last two digits tell the minutes. Hours
The first two digits show 08, which means the hours is 8. The last two digits show 35, which means the minutes is 35. Therefore, the time is 8:35 a.m. Minutes 169

DRAWING LINES OF SYMMETRY
MA.3.GR.1.3 Draw line(s) of symmetry in a two-dimensional figure and identify line-symmetric two-dimensional figures. A line of symmetry divides a figure into two equal halves that have the same shape and same size. You can fold the figure along the line of symmetry and each half will perfectly fit (all sides and vertices match). Example: Draw the line of symmetry of this rectangle.
If you draw a vertical line along the middle of the rectangle and fold it along the line, you can see that each half fits perfectly along the other half.
Similarly, if you draw a horizontal line along the middle of the rectangle and fold it along the line, you can see that each half also fits perfectly along the other half.
But if you draw a line along the diagonal of the rectangle and fold it along the line, you can see that each half does not fit perfectly along the other half (sides and vertices are not matched).
Therefore, the diagonal is not a line of symmetry of a rectangle. 201

EXPLORING AREA AS AN ATTRIBUTE OF TWO-DIMENSIONAL FIGURES
MA.3.GR.2.1 Explore area as an attribute of a two-dimensional figure by covering the figure with unit squares without gaps or overlaps. Find areas of rectangles by counting unit squares. Use partitioning to divide a rectangle into unit squares. The length of the rectangle tells you how many equal columns you should divide the rectangle, while the width tells you how many equal rows you should divide the rectangle. Count the number of squares the rectangle has to determine its area. Example: Find the area of this rectangle.
8 4 The length of the rectangle is 8. So, divide the rectangle into 8 equal columns. Indicates the number of columns
8 4
The width of the rectangle is 4. So, divide the rectangle into 4 equal rows.

DETERMINING THE AREA OF A RECTANGLE MA.3.GR.2.2 Find the area of a rectangle with whole-number side lengths using a visual model and a multiplication formula. To find the area of a rectangle, partition it into unit squares by dividing the rectangles into equal columns and rows. The dimensions of the rectangle indicate how many columns and how many rows the rectangle must be divided. Then, count the number of unit squares to get the area. Example: Find the area of this rectangle.

SOLVING PROBLEMS INVOLVING AREA AND PERIMETER
MA.3.GR.2.3 Solve mathematical and real-world problems involving the perimeter and area of rectangles with whole-number side lengths using a visual model and a formula. When solving mathematical and real-world problems involving the perimeter and area of a rectangle, follow these steps for better understanding of the question.
Example: A rectangular garden is 9 feet long and 6 feet wide. Find the perimeter and area of the garden.
STEP 1
Identify the necessary information. Circle the givens in the problem and underline what needs to be figured out.
A rectangular garden is 9 feet long and 6 feet wide. Find the perimeter and area of the garden. 9 feet
STEP 2
If none is provided, draw a figure to represent the situation.
6 feet
Determine whether the problem is asking for the perimeter or the area. Perimeter refers to the boundary around the rectangle. Area refers to the space the rectangle occupies. Perimeter = 2 × (9 + 6) = 2 × 15 = 30 feet Use the formula to find the perimeter of the garden:
Area = 9 × 6 = 54 square feet
9 feet
Perimeter = 2 × (length + width) STEP 3
Partition the rectangle into unit squares, or use the formula to find the area:
6 feet
Area = length × width
STEP 4
225
Write your final answer. Do not forget to write the units.
Therefore, the perimeter of the garden is 30 feet and the area is 54 square feet.

FINDING PERIMETER AND AREA OF COMPOSITE FIGURES MA.3.GR.2.4 Solve mathematical and real-world problems involving the perimeter and area of composite figures composed of non-overlapping rectangles with whole-number side lengths. To find the perimeter of a composite figure, add the lengths of all sides. Be aware that the lengths of all the sides are not always given but can be derived based on the lengths of the other sides.
Example: Find the perimeter of the figure. Notice that the dimension of the bottom side is not given. We can find this length using the lengths of the top side and middle horizontal side. Since the top side is 8 and the middle horizontal side is 4, then the bottom side is 8 - 4 = 4 units.
To find the area of a composite figure, decompose the figure into two or more rectangles. Then, find the areas of these smaller rectangles and add the areas to find the total area of the figure. Be aware that the lengths of all the sides are not always given but can be derived based on the lengths of the other sides.
Example: Find the perimeter of the figure. Notice that the dimensions of the bottom side is not given. We can find this length using the lengths of the top side and middle horizontal side. Since the top side is 8 and the middle horizontal side is 4, then the bottom side is 8 - 4 = 4 units. We can then decompose this figure into two rectangles. One rectangle has an area of 6 × 4 = 24 square units, and the other rectangle has an area of 4 × 3 = 12 square units. Therefore, the area of the figure is the following: 24 + 12 = 36 square units. 233

COLLECTING AND REPRESENTING DATA MA.3.DP.1.2 Interpret data with whole-number values represented with tables, scaled pictographs, circle graphs, scaled bar graphs or line plots by solving one– and two-step problems. MA.3.DP.1.1 Collect and represent numerical and categorical data with whole-number values using tables, scaled pictographs, scaled bar graphs or line plots. Use appropriate titles, labels and units. Follow the following steps to interpret information presented in scaled pictographs, circle graphs, scaled bar graphs, or line plots. To read information from scaled pictographs, pay close attention to the key. The key tells how much each picture represents.
Each section in a circle graph shows the relative size of that section compared to the whole. We can see the following: •Blue won 20 medals •Green won 26 medals
The key shows that each represents 4 medals; this means represents 2 medals. Since the Green Team has six means Green Team won.
and one , this
(4 × 6) + (1 × 2) = 24 + 2 = 26 medals To read information from scaled bar graph, check the size of each bar on the graph. The bars also show the relative size of data compared to each other. The bar for Green is halfway between 24 and 28 medals, which means Green won 26 medals. Based on the sizes of each section, we can also see that Yellow won the most medals because the bar for Yellow is the tallest. Red won the least medals because the bar for Red is the shortest. 241
•Red won 12 medals
Based on the sizes of each section, we can also see that Yellow won the most medals because the section for Yellow is the largest section. Red won the least medals because the section for Red is the smallest section. To read information from a line plot, count the number of dots representing each category.
Based on the line plot, we can see that 1 student is 36 inches tall because there is only one dot above 36. We can also see the 3 students are 40 inches tall because there are three dots above 40. We can also see that there are ten dots in the line plot, which means this line plot represents the heights of ten students.
