Using an abacus if you are visually impaired
I was taught to use the abacus at the Western Pennsylvania School for Blind Children in the late 1960’s, and I still use it occasionally, just to keep in practice.
Last Saturday evening, my wife Lee was beating me at Scrabble, and I was keeping score with my old “beady buddy”, as my teacher used to call it. It lacks the sophistication and power of a talking calculator, but it is a wonderful tool for addition, subtraction, and other basic math functions.
The type used by people who are blind contains a felt pat under the columns, enabling the user to examine where the beads are without accidentally moving them.
In my next entry, I’ll put the abacus into its proper perspective by telling you about what I used before the “beady buddy” came along. Ever heard of a Cubarithm board?
