Make a Friendly Ten: Add Using Compensation #1

Don’t let two-digit addition intimidate you; instead, use compensation to make friendly tens! In this worksheet, learners will be asked to solve 12 addition problems by taking a number from one addend and adding an equal number to the other, creating a simpler equation they can use to find the sum. An example shows students how they are meant to complete each problem. 

This worksheet is a great resource for second graders stepping into two-digit addition. The ability to adjust addends to create multiples of ten can make addition simpler and more efficient. This worksheet encourages students to use strategic thinking to decide what to add to and subtract from the addends. It can also help learners develop their mental math skills!
