## HMH Into Math Grade 1 Module 5 Lesson 2 Answer Key Represent Change Unknown Problems with Objects and Drawings

I Can add or subtract to solve word problems when the change is unknown and represent the problem with objects, drawings, and equations. How would you solve this problem?  Explanation:
The children selected the number 6,
Wrote the number 6 in the blank
After adding some more oranges to the basket it has 16 oranges now
Subtract 6 from 16
16 – 6 = 10

Children work in pairs. Have one child choose a number from 6 to 9. Tell them this is the number of oranges in a basket and have them write their number. Then tell them that more oranges are added to the basket and now there are 16 oranges in the basket. Have them find how many oranges were added and draw to show what they did.

Question 2.
Yuna has flags from 16 countries. She gives some to her brother. Now she has 7 flags. How many flags does Yuna give her brother? Draw to show your thinking.
____ flags
9 flags

Explanation:
Yuna has flags from 16 countries

Question 3.
Model with Mathematics Martin has 5 clean socks. He gets some more clean socks. Now he has 12 clean socks. How many clean socks does he get?
Equation: ______
Martin gets ___ clean socks. Martin gets 7 clean socks

Explanation:
Martin has 5 clean socks
He gets some more clean socks
Now he has 12 clean socks
To find the number of clean socks she gets
Subtract  5 from 12
12 – 5 = 7
The equation that matches with the problem is 5 + 7 = 12
Therefore, Martin gets 7 clean socks.

Question 4.
7 + ___ = 14
7 + 7 = 14

Explanation:
Subtract 7 from 14
14 – 7 = 7
So, the sum of 7 and 7 is 14
Therefore, 7 + 7 = 14.

Question 5.
13 – ___ = 4
13 – 9 = 4

Explanation:
Subtract 4 from 13
13 – 4 =9
So, the difference of 13 and 4 is 9
Therefore, 13 – 9 = 4.

Question 6.
9 + ___ = 17
9 + 8 = 17

Explanation:
Subtract 9 from 17
17 – 9 = 8
So, the sum of 9 and 8 is 17
Therefore, 9 + 8 = 17.

Question 7.
14 – ___ = 5
14 – 9 = 5

Explanation:
Subtract 5 from 14
14 – 5 = 9
So, the difference of 14 and 5 is 9
Therefore, 14 – 9 = 5.

Question 8.
13 = 6 + ___
13 = 6 + 7

Explanation:
Subtract 6 from 13
13 – 6 = 7
So, the difference of 13 and 6 is 7
Therefore, 13 = 6 + 7.

Question 9.
12 – ___ = 9
12 – 3 = 9

Explanation:
Subtract 9 from 12
12 – 9 = 3
So, the difference of 12 and 9 is 3
Therefore, 12 – 3 = 9.
