Virtual Math Manipulatives

The use of manipulatives, virtual or concrete, can help students build a better understanding of math concepts.  Manipulatives also help students represent about abstract concepts in a concrete way. Teachers then help students to connect these new concepts to their background knowlege.  Some of the advantages of using virtual manipulatives over concrete manipulatives include unlimited numbers or sets of manipulatives and customization.  What are Virtual Manipulatives? by Patricia Moyer, Johnna Bolyard, and Mark Spikell discusses different types of virtual manipulatives, classroom applications, and information about evaluation of virtual manipulative sites.  Learning Mathematics with Virtual Manipulatives also has information about how to use virtual manipulatives in the classroom, efficacy of manipulatives, and information about choosing appropriate manipulatives for teaching a concept.
