## HMH Into Math Grade 2 Module 17 Lesson 2 Answer Key Represent Regrouping for Subtraction

I Can subtract a three-digit number with regrouping using a concrete model or a visual model.

How many nails does Mrs. Orlov have now?

__________ nails
Mrs. Orlov buys 425 nails. She uses 350 nails in a project. How many nails does Mrs. Orlo, have now? Show how you con solve this problem.
75 nails
Explanation:
She uses 350 nails in a project.
let n be the nails that Orlo have
n = 425 – 350
425 – 350 = 75
n = 75
75 nails that Mrs. Orlo, have now

Build Understanding

A scientist finds 318 bats in a cave. Then 176 bats fly away. How many bats stay in the cave?

A. Make a concrete model to show 318 bats. Draw a visual model to show your work.

B. How con you subtract 176 from 318?
THINK: Do I need to regroup?
Show the subtraction in your visual model. Remember to show any regrouping.
We have to regroup in tens place as we cannot subtract 7 from 1
1 becomes 11 after regrouping
11 – 7 = 4

C. Solve the problem.
___________ bats stay in the cave.
142 bats stay in the cave.
Explanation:
We have to regroup in tens place as we cannot subtract 7 from 1
1 becomes 11 after regrouping
11 – 7 = 4
Hundreds are regrouped tens so, 3 hundreds become 2 hundred
2 – 1 = 1

Turn and Talk How is 1 hundred regrouped as 10 tens?

1 hundred = 10 ones.
10 tens can be regrouped to make a hundred and 10 hundreds can be regrouped to make a thousand.

Step It Out

Question 1.
424 – 251 = _______

A. Draw a visual model to represent 424.

B. Do you need to regroup to solve? Explain.
Yes, we need to regroup in tens place.

C. Subtract to solve. Draw on your visual model to help you. Remember to record when you regroup.

Explanation:
The difference of 424 – 251 = 173
We have to regroup in tens place.
we cannot subtract 5 from 2 so, regrouped 2 as 12
12 – 5 = 7

Check Understanding

Question 1.
There are 238 large marbles and 145 small marbles in a bag. How many more large marbles than small marbles are there? Make a concrete model or draw a visual model to solve.

Explanation:
There are 238 large marbles
and there are 145 small marbles in a bag.
238 – 145 = 93
93 more large marbles are there than small marbles

Question 2.
Reason How many more points did the Tigers score than the Eagles? Make a concrete model or draw a visual model to solve.

The Tigers scored _________ more points than the Eagles.

The Tigers scored 33 more points than the Eagles.
Explanation:
Points scored by the tigers = 125
Points scored by the Eagles = 92
The difference of 125 and 92 is 33
so, 33 more points than the Eagles.

Question 3.
Open Ended Complete this subtraction problem so that it will require regrouping 1 hundred as 10 tens. Then solve.

Explanation:
The numbers choose are 833 and 252
we have to regroup in tens and hundreds place.
1 hundred = 10 ones 8 hundreds will change as 7 hundreds.
833 – 252 = 581

I’m in a Learning Mindset!

What did I learn in addition to regrouping hundreds in subtraction?
