I have used Kumon books for my preschool aged kids with great success. They have always been very inclusive yet simple and colorful. So I thought I'd help my 4th grader by trying this Kumon multiplication workbook, albeit sight unseen.
It seems to be all multiplication problems - page after page. There is nothing interesting or compelling about it, just drill. No games, no colorful diagrams, nothing intriguing or engaging. For some kids, this might be a good match for their needs, but it wasn't really what I was looking for.
