Arithmetic Tutorials

The focus of these animated tutorials is to help students understand the operations used in Arithmetic, rather than just memorizing the steps. This is accomplished through the use of visualization and animation to connect the algorithms to common manipulatives found in elementary classrooms.

All tutorials designed and created by: Sue Glascoe

These tutorials were designed to help students visualize the concepts of arithmetic using concrete tools/objects and animation (the animations require the Flash plug-in for your browser). I originally created them to be used as tutorials for my Math For Elementary Teachers course (MAT 156) at MCC, but I believe they will also be useful for students having difficulty understanding some of the topics in arithmetic. They are strictly introductory in nature; helping students visualize the basic concepts, rather than to challenge their skills.
