My children and I love the worksheets. It's very colorful, fun and educational. I did order the teacher's book with this. The teacher's book really explains good ways to teach your preschooler. I really recommend buying the teacher's book along with this student's book. My only complained is that the teacher's book, the art and craft section requires supplies that is hard to get. So, I got art and craft ideas off the internet for my preschoolers.
