The library has 1,000 travel books. There are fewer than 100 United States travel books. The rest of the books are international travel books. How many United States travel books and international travel books could the library have?
HMH Into Math Grade 3 Module 10 Lesson 2 Answer Key Use Place Value to Add 1
Write an equation to model the problem. Show your work.
Answer:
The library has 1,000 travel books. There are fewer than 100 United States travel books.
fewer than 100 be 90
let n be the international books
n + 90 = 1000
n = 1000 – 90
n = 910

Turn and Talk Suppose the library has 276 United States travel books. How many international travel books does the library have? How do you know?
Answer:
let n be the international travel books
n + 276 = 1000
n = 1000 – 276
n = 724

To regroup is to exchange amounts of equal value to rename a number.
Examples:
17 ones → 1 ten 7 ones
13 tens → 1 hundred 3 tens

C. How can you regroup in each column? Record. Explain how you regrouped.
HMH Into Math Grade 3 Module 10 Lesson 2 Answer Key Use Place Value to Add 4

398 + 54 = 452 are on the ferry

Question 2.
The Delgados travel by airplane from Houston, Texas, to Orlando, Florida. Then they travel by bus from the airport to a hotel. Distances are shown on the map. How many miles do the Delgados travel?
HMH Into Math Grade 3 Module 10 Lesson 2 Answer Key Use Place Value to Add 5
A. What equation can you write to model the problem?
Answer:
let the total distance be n
Distance travelled in flight is 849
Distance travelled in bus is 27 miles
n = 849 + 27
n = 876

B. Write the problem in the chart. Add the ones. How can you regroup and record the ones? Explain. Add the tens. Then add the hundreds. Record.
HMH Into Math Grade 3 Module 10 Lesson 2 Answer Key Use Place Value to Add 6
Answer:

C. How many miles do the Delgados travel?
Answer:
Delgados travel 849 + 27 = 876
that they travel.

D. Show how can you use expanded form and partial sums to check your work. How is this like using place value to add? How is it different?
Answer:
876 is written as 800 + 70 + 6
8 hundreds 7 tens 6 ones.

Turn and Talk If the Delgados drive 12 miles from the hotel to a state park, do you need to regroup to find the total number of miles? How do you know?
Answer:

Explanation:
If the distance by bus is 12
then the equation changes by
n = 849 + 12
n = 861
