Why Do We Regroup?

We will continue to discuss the idea of regrouping in class.  Today, we learned how to use an interactive online application to see regrouping in action.  Ask your child to create an addition question and explain regrouping using the link called "Base Ten Addition" on the top right of the page.  When you open the link, you may have to read the instructions if you are having trouble with it; I had to read them to remember how to work the application.
