How to use the relationship between multiplication and division to solve math word problems is the focus of the lesson presented here. In it, fourth graders work in groups to solve problems posed by the teacher. Then, each group is given paper cups and uses them as a manipulative to solve another problem. Finally, each group completes the problems on a worksheet entitled, "What to do with Remainders," and shares their results with the class. Other terrific worksheets are embedded in this fine plan.
