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. This book goes over letters both upper and lower, numbers, colors, shapes, finding things, etc. It even has a bit for critical thinking which I really like. The book is done in sections like all the letters are together. So what I did was get whatever letter we were on and then a line work page to do with it. Or a shapes page with a colors page. That way it wasn't just all of one section from the book at a time. Bur you can really do this book however works best for your child.
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 planning on reusing the book for our next child but since it was only 9$ I didn't mind actually writing on the pages. I was so surprised 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. My youngest is 2 now and not ready for this kind of work yet and that is completely fine. It is important to not compare one child to another. Popcorn all goes in the microwave but pops at different times.
