Complete the Compensation, Then Add!

Sharpen your mental math skills by using compensation to add! In this worksheet, students will complete 10 addition problems using compensation. One addend has already been turned into a multiple of 10. Learners must properly use compensation to adjust the second addend, then use mental math to find the sum.The first problem has been completed to guide students’ efforts.

This resource will help second graders become familiar with the compensation strategy. By adjusting one addend to a multiple of 10, learners can complete two-digit addition problems with efficiency and confidence. As students build their addition and mental math skills, they can feel empowered to tackle larger problems.
