Adaptable Abacus

Most concepts from K-8 can be shown on a simple abacus. My patented abacus enhances the capabilities of the traditional 100 bead abacus in several ways. First of all, it is larger to serve as a better instructional tool for teachers. It is also wider to allow for greater separation of the beads. And, finally, it is adaptable in its bead arrangments and it even has some very special beads. It is called the ’10 blocks 100 beads’ adaptable abacus and it will be coming for sale soon!
