[Blindmath] Teaching calculation algorithms to blind students

Years ago I resisted teaching the abacus to my students, thinking it would be obsolete, but it still an excellent tool for the children. When I found the 'counting method, it changed my life!! It makes so ,much sense.

In terms of integrated students, I try to get my students using the abacus solidly, so that they can use it in the classroom. They end up, sometimes calculating faster than the rest of the class.
