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.
I was honestly disappointed in this book. My 4yo daughter is bored by so much of it. I was looking forward to the Christian perspective but unless you have the teacher's book, it's not there. There are lots of crafts, coloring, cutting and the like which just makes her 5 yo old brother wonder why he does not get to do that. We skip a lot, as we do craft projects with all the kids. It might be good if you had one child in school and you had the teacher's book. I think for my next child I will buy some colors, shapes, numbers books and work with her in real life situations.
