Review on 📚 Boost Math Skills with Channies Beginner Multiplication Practice Workbook by Trey Michaels

Love it. My son was in Kumon for the summer and when school started we stopped Kumon because he was too busy. We went on to double digit and one to one multiplication and he did them all on his own and voluntarily. The format allows them not to mix up places when writing an answer. That's exactly what Kumon does (repeatedly until you memorize it). It's definitely worth every penny.
