Complete Abacus Mind Math: Step by Step Guide to Mastering Mind Math with a Japanese Abacus Paperback – 2 Oct. 2017

Easy read informative good buy

Very good for children to learn from.

This is a very helpful book to use whilst teaching the Abacus. However, I dislike the quality of print. But the lessons, worksheet pages and diagrams are excellent. My grandson doesn't like it as much as our other one, but I think the instruction and how to's are really good and helpful. Its quite a big book. I would like it to help with more than just addition and subtraction, or at least to do a second one on those topics. But for addition and subtraction it is very good.
