Unifix cubes have long been recognized as a manipulative of choice for teaching beginning math concepts. While not as versatile as multilinks (as Unifix Cubes snap together only on top and bottom), they are easier for small children to link together and take apart. Use them for counting, adding, subtracting and other math functions. There are a wide range of sets and materials available to choose from. We have selected what we believe to be the most useful, versatile, and inexpensive to fill your needs.
