HMH Into Math Grade 2 Module 17 Lesson 1 Answer Key Represent Three-Digit Subtraction
(I Can) subtract a three-digit number without regrouping using a concrete model or a visual model.
Spark Your Learning
What is Matt’s point total? Show your work with a visual model.
Noura and Matt play a video game. Noura’s points total has 3 hundreds, 8 tens, 7 ones. Matt’s points total is 5 tens 3 ones less than Noura’s points total. How many points does Matt score?
3 hundreds, 8 tens, 7 ones = 387
Noura’s points = 387
Matt’s points is 53 less than Noura’s points
387 – 53 = 334
so, Matt score 334 points.

Step It Out
The children’s theater had 876 tickets to sell. There are 352 tickets left to sell. How many tickets were sold?
A. Draw a visual model to represent 876.
B. Show how to subtract 352 from 876 in your drawing.
C. How many hundreds, tens, and ones are there?
__________ hundreds _________ tens ________ ones
5 hundreds 2 tens 4 ones
D. Solve. How many tickets were sold?
The children’s theater had 876 tickets to sell.
