The ABLE-I electronic calculator consists of the ABLE calculator base unit and one of the six colorful, interchangeable snap-on keyboard faces delivered with the ABLE.

The ABLE-I limits the functions of a standard calculator by supporting only few keys:

[0] – [1], [+], [=], [C]

In conjunction with K-1 “Elementary Mathematics Concepts with Calculators”, a supplementary learning program for kindergarten/first grade students developed my math educators at the University of California ’s Lawrence Hall of Science, the uses include:

•Counting Tallying
•Counting with 2’s, 3’s, 4’s, 5’s
