## New York State Common Core Math Module 1, Grade 4, Lesson 13

### NYS Math Module 1 Grade 4 Lesson 13 Concept Development

Problem 1:
Use a place value chart and disks to model subtracting alongside the algorithm, regrouping 1 hundred into 10 tens.
4,259 – 2,171 =

Problem 2:
Regroup 1 thousand into 10 hundreds using the subtraction algorithm.
23,422 – 11,510 =
Repeat for 29,014 – 7,503.

Problem 3:
Solve a subtraction application problem, regrouping 1 ten thousand into 10 thousands. The paper mill produced 73,658 boxes of paper. 8,052 boxes have been sold. How many boxes remain?
Repeat with: The library has 50,819 books. 4,506 are checked out. How many books remain in the library?

### NYS Math Module 1 Grade 4 Lesson 13 Problem Set

1. Use the standard algorithm to solve the following subtraction problems.
a. 7,525 - 3,502 =
d. 4,625 - 435 =

Directions: Draw a tape diagram to represent each problem. Use numbers to solve and write your answer as a statement. Check your answers.
2. What number must be added to 13,875 to result in a sum of 25,884?
4. During the month of March, 68,025 pounds of king crab were caught. If 15,614 pounds were caught in the first week of March, how many pounds were caught in the rest of the month?
