Actually, I have found the cranmer abacus at aph as Ken suggests. I'm
looking for a ten bead abacus but I don't know what that's called. I think
math makes more sense to kids when there are ten beads. The value of the
cranmer was in speed of use but in early learning I liked the ten bead.

Mike, are you talking about a Cranmer abacus, or something different?
