FAMILY MATH Count and Compare with Data Dear Family, Your student is using graphs to organize, represent, and interpret data. They collect data by counting various things.

Then they represent, or show, the data in different graphs and charts. Your student is also interpreting graphs and charts by comparing the categories. They use the greater than (>) and less than (<) symbols to write comparison number sentences.

At-Home Activities Organize and Compare Prepare a disorganized pile of two or three types of objects, like forks and spoons. Ask your student to predict whether there are more of one object or the other. Then, have your student line up the objects in separate rows and count the number in each row to check their prediction. Encourage your student to use comparison statements like the following examples to describe the relationship between the groups.

•

“There are 4 spoons and 7 forks. 4 is less than 7. There are fewer spoons than forks.”

•

“There are 4 spoons and 4 forks. 4 is equal to 4. There is an equal number of forks and spoons.”

Make a Graph Collect data about objects around you, such as the number of buttons, pockets, and zippers on your clothing or your student’s clothing. Invite them to graph the data by creating a picture graph or tally chart. The graph can help your student to organize and compare the data. Help your student analyze the data by asking the following questions.

4

•

“How many buttons are on your clothes? How many pockets are on your clothes?”

•

“Do you have more buttons or more pockets? How do you know?”

Module 1 Topic B

FAMILY MATH Count On from a Visible Part Dear Family,

Key Terms

Your student is practicing the addition strategy of counting on doubles from a known part to find the total. For example, the dice in unknown the images show two parts, 5 and 2. Rather than counting all the dots, they start with a part they know and count on from that number to find the total. As they count on, they may point to the dots or use their fingers to keep track of the counts. Starting with the larger part, such as 5, is more efficient, but your student discovers that counting on from either part results in the same total. Your student learns that the number we are trying to figure out is called the unknown, and that when both parts are the same number, they are called doubles.

Fiiiive, 6, 7

Twoooo, 3, 4, 5, 6, 7

5 dots are on one die.

Count on 2 more dots.

2 dots are on one die.

Count on 5 more dots.

5+2=7

2+5=7

At-Home Activities Let’s Count On Gather a set of 10 objects such as coins, marbles, or cups. Arrange the objects into two groups with an easily countable pattern, like dots on dice or dominoes. Ask your student to find the total by counting on by asking these questions. After your student has counted, note that the total stays the same no matter which group they started with.

•

“How many objects are in this group?”

•

“Can you count on from that number to find the total of both groups?”

•

“What would change if you started counting with the other group?”

“This new box of granola bars holds 10 bars. The open box in our cabinet still has some bars in it. Can you count on from 10 to find how many bars we have in all?”

Module 1 Topic C

FAMILY MATH Count On to Add Dear Family,

Key Terms

Your student is learning to find the total of an addition expression, such as 8 + 3. Your student counts on from a part to find the total just like they did when finding the total of a set of objects. They confirm that they can add in any order and come to recognize that counting on from the larger part is more efficient. When counting on, your student uses their fingers or a number path. They are also introduced to telling time on an analog clock. Your student will revisit telling time throughout the year.

When the longer minute hand is pointing to 12 and the shorter hour hand is pointing to 3, we say 3 o’clock.

At-Home Activities More and Some More Look for opportunities to practice counting on during everyday situations such as when folding laundry, during a trip to the grocery store, or on a walk in the neighborhood. Consider the following examples.

•

“I have 5 socks in this pile. Count on from 5 as you put some more socks in the pile.”

•

“I have 3 apples in the cart. Count on from 3 as you put more apples in the cart until we have 7 apples.”

•

“I see 4 mailboxes. Count on until you see 10 mailboxes.”

What Do You See? Take turns practicing adding numbers within 10 with your student. Use variations of animals to add different amounts together that make totals that are 10 or fewer. Consider the following examples.

•

“I see 3 camels and 2 tigers. What 5 animals do you see?” (I see 4 lions and 1 tiger.)

•

“I see 2 seals and 5 monkeys. What 7 animals do you see?” (I see 4 bears and 3 penguins.)

•

“I see 6 elephants and 4 otters. What 10 animals do you see?” (I see 7 kangaroos and 3 rhinos.)

Consider taking turns going first so your student can determine the first combination of animals.

FAMILY MATH Make the Same Total in Varied Ways Dear Family,

Your student is learning about the meaning of the equal sign. They learn that an equal sign means that the expression or number on either side of the sign have the same total. This is important so your student doesn’t only think of the equal sign as a signal for an answer. Your student continues exploring different expressions with the same total by finding all of the ways to add two numbers to make any value from 0 to 10. They also build on their work with doubles facts to find the total of doubles +1 facts.

5+1=2+2+2 1+4

=

True

The cubes show that the totals on each side of the equal sign are the same.

2 + 5 = 3 +3 7

6

False

If the totals on each side of the equal sign are the same, the number sentence is true. If the totals on each side of the equal sign are not the same, the number sentence is false.

At-Home Activities Number Names Look for or think of places or things common to you that have numbers in their names.

Examples include the names of stores or roads. Then rename the place or thing you chose by breaking apart the number. For example, Route 9 can be renamed as Route 7 + 2, or the game four square can be renamed as 3 + 1 Square. See if you and your student can think of all the different combinations for the number.

Seeing Doubles +1 You and your student can look at magazines, picture books, or anywhere in daily life for images with things in sets of 2s, 3s, 4s, or 5s. Then take turns doubling the amounts you see and adding 1.

MATH IS EVERYWHERE Do you want to compare how fast you and your friends can run?

Or estimate how many bees are in a hive?

Or calculate your batting average?

Math lies behind so many of life’s wonders, puzzles, and plans.

From ancient times to today, we have used math to construct pyramids, sail the seas, build skyscrapers—and even send spacecraft to Mars.

Fueled by your curiosity to understand the world, math will propel you down any path you choose.

Ready to get started?

Module 1 Counting, Comparison, and Addition Module 2 Addition and Subtraction Relationships Module 3 Properties of Operations to Make Easier Problems Module 4 Comparison and Composition of Length Measurements Module 5 Place Value Concepts to Compare, Add, and Subtract Module 6 Attributes of Shapes • Advancing Place Value, Addition, and Subtraction

What does this painting have to do with math?

American realist Edward Hopper painted ordinary people and places in ways that made viewers examine them more deeply. In this painting, we are in a restaurant, where a cashier and server are busily at work.

What can you count here? If the server gave two of the yellow fruits to the guests at the table, how many would be left in the row? We will learn all about addition and subtraction within 10s in Units of Ten.
