Created by a team of researchers and educators at Utah State University with support from the National Science Foundation, this new online library of interactive manipulatives is intended to help educators accomplish the often challenging task of engaging students in daily math lessons. Whether you’re teaching basic mathematical concepts, from simple algebra or geometry to units of measurement, or more advanced lessons on topics such as data and probability, chances are you’ve found yourself in a situation where, no matter what you do, your students seem either unable, or unwilling, to grasp the concept. Because learning and understanding mathematics at every level requires student engagement, the researchers behind this three-year project have set out to create a vast library of manipulatives, or learning tutorials, intended to help students visualize and apply these often difficult mathematical concepts. Through the use of Java-based mathematical tools and editors, the site challenges teachers to create and integrate a variety of new approaches to interactive mathematics instruction.
