Teachers of mathematics for centuries have helped students understand mathematics using “manipulatives”-- visual objects that help illustrate mathematical relationships and applications. Manipulatives allow students to visually examine, explore and develop concepts.

The National Library of Virtual Manipulatives (NLVM) at Utah State University has transported these powerful teaching tools into the virtual dimension of the computer. The NLVM collection of over 100 interactive software programs, called “applets,” are an effective means for accelerating and deepening students' understanding of math.

The NLVM development team consists of mathematicians, math educators and instructional design experts at Utah State University.

The National Science Foundation provided funding for creation of the National Library of Virtual Manipulatives and eNLVM.

Ongoing development of new activities and functionality is supported by NLVM retail sales.

MATTI Math was founded as MATTI Associates LLC in 2001. The Utah-based partnership’s purpose is to select quality educational software and facilitate awareness and distribution to applicable markets. The National Library of Virtual Manipulatives CD is its premiere product. MATTI Math will be distributing products that add to the NLVM’s functionality, as well as future additions to the NLVM’s activities.

MATTI Math is the NLVM’s official licensee, expanding distribution and supporting ongoing development of this award-winning resource.

The National Library of Virtual Manipulatives has received numerous honors, including:

- Math Forum Hot Spot of the Month

- Education World, Best of 2001

- Math Cats Spotlighted Website

- Techlearning Site of the Day

- Eisenhower National Clearinghouse for Mathematics and Science Education Digital Dozen
