This file contains materials for four activities to practice double digit addition with regrouping:
1. A practice page with guided practice problems to do as a class and independent practice problems for students to try individually
2. An independent practice cut and paste puzzle activity
3. A tic tac toe game students can play with a partner to practice adding two digit numbers
4. Materials for a puzzle center
The practice page and tic tac toe game also include a few problems that don't require regrouping to help students practice determining whether or not regrouping is necessary.
Problems are written in a table format that gives students space to regroup and makes it easier to keep their ones and tens columns lined up. (See preview for an example.)
Answer keys included.
