## HMH Into Math Grade 2 Module 12 Lesson 4 Answer Key Represent and Record Two-Digit Subtraction

I Can represent and record two-digit subtraction with and without regrouping.

How can you show the problem? How many goldfish are at the store now?

There are _________ goldfish at the store now.
Read the following: There are 37 goldfish at the pet store. Then Mrs. Clark sells 15 goldfish. How many goldfish are at the store now?
Given that,

Question 1.
Serena has 52¢. Then she pays 35¢ for a snack. How much money does she have now?

A. How can you use tools to show 52? Draw to show what you did.

Given that,
Serena has money = 52 cents.
Serena pays for snack = 35 cents.

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 2 and subtrahend is 5.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

B. If there are not enough ones to subtract 5, regroup I ten as 10 ones. How can you show the regrouping in your drawing above?

52 – 35 = 17
Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 2 and subtrahend is 5.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

C. How can you subtract the ones? Show your work in your drawing above. Write the number of ones left in the ones place.
After regrouping in the one’s place, the numbers are 12 and 5, 12 – 5 = 7.
The number of ones in the one place is 7.

D. How can you subtract the tens? Show your work in your drawing. Write the number of tens left in the tens place.
After regrouping in the tens place, the numbers are 4 and 3, 4 – 3 = 1.
The number of tens in the tens place is 1.

E. Solve the problem. _________ ¢
Given that,
Serena has money = 52 cents.
Serena pays for snack = 35 cents.

Question 2.
Martha and her friends make a list of two-digit numbers. She chooses two of the numbers to subtract.

A. How can you draw quick pictures to help find 41 – 28?

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 1 and subtrahend is 8.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

B. How can you subtract the ones? Regroup if you need to. Show your work in the chart.

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 1 and subtrahend is 8.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.
In the ones place 11 – 8 = 3

C. How can you subtract the tens? Show your work in the chart.
41 – 28 = 13
Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 1 and subtrahend is 8.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.
In the tens place 3 -2 = 1

D. What is the difference?
41 – 28 = 13
The difference is 13.

Turn and Talk How do you know when you need to regroup a ten to subtract ones?
You need to regroup when the top digit in the one’s place is smaller than the bottom digit in the one’s place then you need to regroup a ten to subtract ones.

Step It Out

Question 1.
Subtract 36 from 64.

A. Subtract the ones. Regroup if you need to. Complete the chart to show your work.
_________ – 6 = _________

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 4 and subtrahend is 6.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.
In the ones place 14 ones – 6 ones = 8 ones.

B. Subtract the tens. Complete the chart to show your work.
_________ – 3 = __________
After regrouping in subtraction
5 – 3 = 2 tens.

C. Write the difference. _________
64 – 36 = 28.
28 is the difference.

Brett and his friends have 52 grapes. They eat some grapes for a snack. Now they have 24 grapes. How many grapes do Brett and his friends eat? Draw to show the subtraction. Solve.

__________ grapes
Brett and his friends have 52 grapes.
Brett and his friend have eaten some grapes as snacks.
Now they have 24 grapes.
Brett and his friend ate grapes = 52 – 24 = 28.
Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 2 and subtrahend is 4.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

Question 2.
Reason There are 47 dog treats in a box. Then Connie and her family give 29 treats to their dogs. How many treats are in the box now? Draw to show the subtraction. Solve.

_________ treats
Given that,
The total number of treats in a box = 47.
Then Connie and her family give to their dogs = 29
Number of treats in the box = 47 – 29 = 18.
Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 7 and subtrahend is 9.
We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

Question 3.
Subtract 42 from 76

Here we no need to regroup. Because the minuend is greater than the subtrahend.
The minuend is 7 and subtrahend is 4.

Question 4.
Subtract 8 from 64

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.
The minuend is 4 and subtrahend is 8.
