Compensation Addition Worksheets

Second Grade math worksheets to help students practice compensation addition.
Compensation addition is a mental math strategy that involves adjusting one of the numbers in a problem to make the addition easier, and then adjusting the final answer to compensate for the change.

1. Look for a number that can be easily altered to a multiple of 10, to create a more convenient addition problem.
2. Make the adjustment to the numbers (by adding or subtracting a small number).
3. Solve the adjusted Problem by performing the addition using the modified numbers.

Example:
48 + 37
Adjust 48 to 50: Add 2 to make a multiple of 10.
Adjust 37 to 35: Subtract 2 from 37.
Add the adjusted numbers: 50 + 35 = 85
