This book was hard to find anywhere else. My daughter's preschool loves this book. They feel very proud to do their "homework" in this book. It is very easy and has large illustrations perfect for this age group.
This book is not as challenging as I would have liked. I bought it for my 4 year old and since getting it two weeks ago, she is almost done with it. Would be great for a 3 year old, but a little too easy for a 4-year old. Also wish the book was longer.
