Abstract

See full text

A portable and foldable teaching aid combines an abacus and an inclined writing surface. The abacus helps teach math skills and the inclined writing surface helps strengthen hand and wrist muscles that are used in writing. The abacus and writing board are positioned in physical proximity to one another to encourage children to write down math problems on the writing board, to solve them on the abacus, and to write down the answer on the writing board. The writing board may be of the dry erase type, the chalkboard type, or any other suitable, erasable writing surface. It may also be magnetized to hold letters, shapes, and the like. The writing board is releasably attached to support rods so that it can be separated from them when the device is folded for storage. When folded, it can be carried separately or placed into a child's backpack.
