### Eureka Math Grade 2 Module 6 Lesson 3 Problem Set Answer Key

Question 1.
Write a repeated addition equation to match the picture. Then, group the addends into pairs to show a more efficient way to add.

a.
____ + ____ + ____ + ____ = ____
\        /          \       /
______ + ______ = _____

4 groups of _____ = 2 groups of _____
There will be 4 groups of 3 snails which can also be written as 2 groups of 6 snails.

Explanation:
In the above image, we can see that there are 4 groups, and in each group, we can see that there are 3 snails. So the addition equation to show the number of objects in each group is 3 + 3 + 3 + 3 = 12 snails. So there will be 4 groups of 3 snails which are 12 snails and the efficient way to add is 6 + 6= 12 snails and also can be written as 2 groups of 6 snails.

b.
____ + ____ + ____ + ____ = ____

____ + ____ = ____

4 groups of ____ = 2 groups of ____
There will be 4 groups of 2 chicks which can also be written as 2 groups of 4 chicks.

Explanation:
In the above image, we can see that there are 4 groups, and in each group, we can see that there are 2 chicks. So the addition equation to show the number of objects in each group is 2 + 2 + 2 + 2 = 8 chicks. So there will be 4 groups of 2 chicks which are 8 chicks and the efficient way to add is 4 + 4= 8 chicks and also can be written as 2 groups of 4 chicks.

c.
____ + ____ + ____ + ____ + ____ + ____ + ____ + ____ = ____

____ + ____ + ____ + ____ = ____

8 groups of ____ = 4 groups of ____
There will be 8 groups of 2 chicks which can also be written as 4 groups of 4 chicks.

Explanation:
In the above image, we can see that there are 8 groups, and in each group, we can see that there are 2 chicks. So the addition equation to show the number of objects in each group is 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 16 chicks. So there will be 8 groups of 2 chicks which are 16 chicks and the efficient way to add is 4 + 4 + 4 + 4= 16 chicks and also can be written as 4 groups of 4 chicks.

Question 2.
Write a repeated addition equation to match the picture. Then, group addends into pairs, and add to find the total.

a.
____ + ____ + ____ + ____ + ____ = ____

____ + ____ + 3 = ____

________ + 3 = ____
The addition equation to match the picture is 3 + 3 + 3 + 3 + 3 = 15 dogs. The other ways to represent the addition equation is 6 + 6 + 3 = 15 dogs and the other way is 12 + 3= 15 dogs.

Explanation:
In the above image, we can see that there are 5 groups, and in each group, we can see that there are 3 dogs. So the addition equation to show the number of objects in each group is 3 + 3 + 3 + 3 + 3 = 15 dogs. So the addition equation to match the picture is 3 + 3 + 3 + 3 + 3 = 15 dogs and the group addends into pairs is 6 + 6 + 3 = 15 dogs and the other way is 12 + 3= 15 dogs.

b.
____ + ____ + ____ = ____

____ + 3 = ____
The addition equation to match the picture is 3 + 3 + 3 = 9 dogs. The other ways to represent the addition equation is 6 + 3 = 9 dogs.

Explanation:
In the above image, we can see that there are 3 groups, and in each group, we can see that there are 3 dogs. So the addition equation to show the number of objects in each group is 3 + 3 + 3 = 9 dogs. So the addition equation to match the picture is 3 + 3 + 3 = 9 dogs and the group addends into pairs is 6 + 3 = 9 dogs.

4 groups of _____ = 2 groups of _____
The addition equation to match the picture is 5 + 5 + 5 + 5 = 20 hearts which will be 4 groups of 5 hearts and 2 groups of 10 hearts.

Explanation:
In the above image, we can see that there are 4 groups, and in each group, we can see that there are 5 hearts. So the addition equation to show the number of objects in each group is 5 + 5 + 5 + 5 = 20 hearts. So the addition equation to match the picture is  10 + 10 = 20 hearts so there will be 4 groups of 5 hearts and 2 groups of 10 hearts.
