My 5 year old son is having trouble writing at school so he started doing Kumon workbooks to improve fine motor skills and hand strength. I was reluctant to buy this workbook because it's for younger kids, but this and the Tracing book were great for him. It probably took him about 30 minutes total to do each book, in two sessions. He is developing fine motor skills without a fight and enjoying it so it's worth the money to me.
