2-Digit Addition with Regrouping Workmat & Recording Page
This 2-Digit Addition Work mat is a great tool when introducing regrouping to students. Students use base-10 blocks to model the addition problems. If there are enough ones to make a new ten then they will mark the box on the work mat and exchange 10 ones for a ten stick. This activity is a bridge between manipulatives and the standard algorithm. Two recording pages are included for small group and independent practice.
