The National Library of Virtual Manipulatives is an online mathematics resource developed and maintained by the Department of Mathematics and Statistics at the Utah State University, America.
The library is cross-referenced by key mathematics concepts and year levels, allowing teachers to efficiently locate the most effective virtual manipulative to enhance mathematical learning in specific year levels. Resources vary from easy to use graphing tools to virtual 3D manipulatives.
Many of the resources could easily be used to allow students to develop digital literacies as described in the
