We have recorded a set of videos teachers can view to learn how to use the manipulatives featured in our *Manipulative Mathematics* activities. (You can read more about the philosophy behind these activities and their unique features on the Manipulative Mathematics Overview page.)

Each video gives a brief overview of one type of manipulative, including:

- the math topic(s) it addresses
- a demonstration of teaching the topic(s) using the manipulative
- suggestions for using it in class
- where to find it, in physical and virtual form

We hope these videos inspire you to use manipulatives with your students!
