Addition with Regrouping

This week the Tigers are working on book 4 in the WRS which means long vowels, and the Thunderbolts are continuing with book 2 which is all about blends. We are also using this week to teach/review addition and subtraction with regrouping.

For many of the students this is a review, but it is such a key concept to understand before moving on in math I thought it would be worth a review. The reason for the "house" or the "castle" is to keep our work neat and lined up properly. For more information on the castle algorithm click here.
