I absolutely love the Big Preschool Workbook by School Zone. It is a very comprehensive book of everything for a preschool student. It has really bright colors and fun pictures that keep my daughter interested. I do have to limit how many pages she can do a day otherwise she’d do the whole book. I tore out the pages and put them in a binder for easy access.
At first for this book I was putting the pages in sheet protectors and using expo markers so that I could reuse them but I found our daughter liked to actual write on them better. I was so suprised at how much she knew already so we did breeze through this workbook very quickly. This book includes so much for little ones. The suggested age is 3-5 but my daughter completed this book when she was 2 so it really depends on how interested your child is and how long their attention span is.
