I use what APH calls the Beginner's Abacus with very young students as
an introduction to the concept of counting with beads. I agree with you
that it is a simpler concept to start with and my students have not had
a problem translating their experience when they graduate to a Cranmer

Do any parents use ten bead abacus's to teach their blind kids math
any more?
I'm familiar with the Cranmer but like the ten bead for small children
because they can add beads up to ten and then replace them with one bead
from the next row, rather than adding up to nine and then "knowing" that
they added another one to get to ten and replacing it.
So, anyway, does anyone use this type anymore?
