# Add 2 Digit to 2 Digit Number with Regrouping within 100

Second graders have so far learned to add 1-digit numbers to 2-digit numbers with regrouping. This exciting double facts  game also works as an interactive worksheet. Children they apply their knowledge of regrouping to add double digit numbers. Regrouping ones to make tens is an essential skill required to work with bigger numbers.

What’s inside?

- Regroup ones as tens to add two 2-digit numbers.

Real-World Application

When your child exchanges 10 unit blocks for a tens block, she’s actually regrouping. Similarly, exchanging 10 dimes for a dollar is regrouping. Understanding addition with regrouping reinforces the concept of place value, which is essential for higher grade math.

What’s next?

Having learned to add two 2-digit numbers, children are now ready to work on addition word problems.
