Addition with Regrouping
Have you found yourself trying to understand the mistakes that a student is making in while performing addition with regrouping? As students get older, the algorithm becomes mandatory but a student won't use a tool that they don't understand. So understanding why the algorithm works becomes imperative especially for addition with regrouping. Because I knew how important understanding the algorithm is for upper level math, I wanted my students to have a firm grasp of why it works and how to use t
