Our Product Reviews

Excerpts from a Product Review by Cathy Duffy

I think Mac's Abacus Basic is most likely to be used as a supplement over a number of years. It teaches basic counting, one-to-one correspondence, recognition of numerals, and numeral writing which are key concepts and skills for young children. It continues from there to teach addition, subtraction, place value, carrying, borrowing, and decimals--concepts that stretch up through fourth and fifth grade. Also, it has a few lessons on measurement and telling time plus many lessons on money. Money receives a lot of attention since it is used to teach decimals.

The way Mac's Abacus is used to teach decimals seems particularly ingenious. It builds on strategies used earlier to teach place value, but it uses images of coins (and eventually bills) to teach decimals. Switching to money helps students transition to this new use of the abacus.

Mac's Abacus and the Mac's Abacus Basic workbook are truly unique in their approach and design.
