regrouping
By second year teacher

Last year when my third graders didn't understand the concept my husband suggested that I use Cheetoes (which represented 10) and soup crackers (which represented ones).

The first day we went over the pages in our book, then I passed out the food. I would ask students to show me thirty five or fourty two. After we did that for a couple of minutes I asked them to trade in a ten for ten ones...we did that for a few minutes then they would show me two numbers. We did this until we worked our way up to using the food to subtract and regroup.

It helped a great deal, but I did still have a few that "didn't get it" until later.

Hope this helped!
