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.

MATTI Math has become the distributor of the award-winning National Library of Virtual Manipulatives (NLVM) that has transported these powerful teaching tools into the virtual dimension of the computer. The NLVM collection of over 100 interactive software programs, called “applets,” is an effective means for accelerating and deepening students’ understanding of math.
