The listing, Addition & Multiplication Wrap-Ups for Back to School has ended.
These were great for my son in elementary school! Children use these to learn their addition and multiplication facts (1 thru 10) in a fun, interactive way on their own and at their own pace. If they get stuck, the back of the "keys" show them where the string should go. Parents/teachers show the children how to use them and then let them "play" with them on their own.
