## HMH Into Math Grade 3 Module 1 Lesson 1 Answer Key Count Equal Groups

I Can count equal groups to find the total number of objects when the number of equal groups and the number of objects in each group is given.

**Spark Your Learning**

Suppose you are building more robots like this one. Choose any number of robots to build. How many wheels do you need?

**Show your thinking.**

Answer:

Explanation:

3 + 3 + 3 = 9

If I build 3 robots with 3 wheels each, I need 9 wheels.

**Turn and Talk** What if you build one more robot? How many more wheels do you need? How many wheels do you need now?

**Build Understanding**

1. Raj makes 5 robots like this one. How many legs do the 5 robots have?

**Show equal groups.**

A. What is the same about each of your groups?

____________________________

____________________________

Answer:

Explanation:

4 + 4 + 4 + 4 + 4 = 20

There are same numbers of legs on each robot.

**Connect to Vocabulary**

Equal groups means that each group has the same number of objects.

B. How can you use the number in each group to find the total number of legs?

______________________________

______________________________

Answer:

I can add the number in each group to find the total number of legs

5 + 5 + 5 + 5 + 5 = 20

C. How many legs do the 5 robots have? ______________________________

Answer:

So, 5 robots will have 20 legs.

**Turn and Talk** What if you are finding the number of legs on 5 robots with 6 legs on each robot? What would you do the same? What would you do differently?

Answer:

If i find the number of legs on 5 robots with 6 legs on each robot

I would make 5 groups of 6 legs

6 + 6 + 6 + 6 + 6 = 30

I would make same number of groups with different number of legs.

2. Aisha makes 4 of these robots. How many wheels does Aisha use?

A. How many robots are there? ____

I need to make 4 groups of 6 wheels to find the number of wheels in all

6 + 6 + 6 + 6

Therefore, Aisha uses 24 wheels to make 4 robots.
