AL Abacus, used with the RightStart™ Mathematics program, now available on your android device! This abacus will teach, not calculate like the Japanese and Chinese abacus. Perfect for visual learners!
This unique double-sided abacus is grouped in fives and tens for quick recognition of quantities. The second side of the abacus focuses on trading to the thousands.
Learn the facts easily by
* visualizing quantities,
* minimizing counting, and
* developing mental strategies.
Those learning arithmetic with the AL Abacus have a better understanding of basic concepts and need less time to master arithmetic. Although children do enjoy using the abacus, it does not become a crutch. Stan, age 5, was asked how much is 11 plus 6. He replied, “17!” When he was asked how he knew, he replied with a grin, “I’ve got the abacus in my mind.”
App has links to sample addition, subtraction, multiplication, and division lessons as well as detailed use information.
