This large abacus with one-inch (2.5 cm) beads measures 23" x 24" (58 cm x 60 cm). Ideal for a class or for a child with special needs. Place it on the floor or on an easel. You can work with addition and multiplication using trading and quantity recognition.

    The giant wooden beads on this abacus have been ideal for my special needs kindergartner. She can easily manipulate the beads, where she had a little trouble with the regular-sized abacus. The wood frame is beautiful and sturdy. The abacus rates 4 stars because the wooden "wires" seem a little flimsy.
