## HMH Into Math Grade 1 Module 3 Lesson 1 Answer Key Represent Addition in Any Order

I Can use objects and draw to show that the sum stays the same when the order of the addends changes.

**Spark Your Learning**

Shawn and Janet build robots. All of their robots are either red or yellow. How can you add the robots?

Answer:

Explanation:

Shawn and Janet build robots

All of their robots are either red or yellow

There could be 6 red robots and 4 yellow robots

The addition equations will be 6 + 4 = 10 or 4 + 6 = 10.

Ask children to color some of the robots red and some of the robots yellow. All the robots should be either red or yellow. Have children write an equation to show adding the red robots and the yellow robots. Then have children write an equation to add the yellow robots and the red robots. What do you notice about the two sums?

**Build Understanding**

Paula scored 4 goals at the soccer game. Cameron scored 2 goals at the soccer game. How many goals did they score?

Answer:

6 goals

Explanation:

Paula scored 4 goals at the soccer game

Cameron scored 2 goals at the soccer game

The addition equations that solve the problem are

4 + 2 = 6 or 2 + 4 = 6

So, they scored 6 goals.

**Connect to Vocabulary**

Change the order of the addends.

8 + 9 = 17

9 + 8 = 17

A. How can you make a concrete model for the problem? Draw to show what you did.

___ + ___ = ___

___ goals

Answer:

Explanation:

I drew to show the sum 8 + 9 = 17

There are 8 counters in one frame and 9 counters in other frame

So, they scored 17 goals

B. How can you change your concrete model to show the addends in a different order? Draw to show

what you did.

___ + ___ = ___

__ goals

Answer:

Explanation:

I drew to show the sum 9 + 8 = 17

There are 9 counters in one frame and 8 counters in other frame

So, they scored 17 goals.

**Turn and Talk** Why is the sum the same when you change the order of the addends? seventy-eight

Lexi won 6 red ribbons and 5 blue ribbons at art shows. How many ribbons did she win?

A. What two addition equations could you use to solve the problem? Show how to change the order of the addends.

Answer:

B. Lexi won __ ribbons.

Explanation:

Lexi won 6 red ribbons and 5 blue ribbons at art shows

I wrote 2 equations by changing the order of addends

6 + 5 = 11 and 5 + 6 = 11

So, Lexi won 11 ribbons.

**Check Understanding Math Board**

**Write two addition equations that can be used to solve the problem.**

1. Ron plants 3 white rose bushes and 9 red rose bushes. How many rose bushes does he plant?

___ = ___ + ___

___ = ___ + ___

___ rose bushes

Answer:

3 + 9 = 12

9 + 3 = 12

12 rose bushes

Explanation:

Ron plants 3 white rose bushes and 9 red rose bushes

I wrote 2 equations by changing the order of addends

So, Ron planted 12 rose bushes in all.

On Your Own

Write two addition equations that can be used to solve the problem. Draw pictures to match the equations.

Question 2.

**Reason** Mrs. Bank has 4 games. Mr. Moon has 5 games. How many games do they have?

___ = ___ + ____

___ = ___ + ____

___ games

Explanation:

Mrs. Bank has 4 games

Mr. Moon has 5 games

I drew 2 ways to show the sum

9 = 5 + 4

9 = 4 + 5

I wrote 2 equations by changing the order of addends

So, they have 9 games in all.

**Write the sum. Change the order of the addends and add again.**

Question 3.

9 + 7 =

Answer:

9 + 7 =

Explanation:

The sum of 9 and 7 is 16

I wrote 2 equations by changing the order of the addends

9 + 7 = 16 or 7+ 9 = 16.

Question 4.

__ = 8 + 5

Answer:

13 = 8 + 5 =

Explanation:

The sum of 8 and 5 is 13

I wrote 2 equations by changing the order of addends

8 + 5 = 13 or 5 + 8 = 13.
