I absolutely love this book! I borrowed it from the library and I have it out with the math material in the classroom. The children in the classroom (preschool) keep coming back to this book and asking me to read it to them. They love the flap that lifts to show the next number underneath, and the illustrations are beautiful. It's fun and just a little funky, and I definitely recommend it.
As a teacher, I love that the number sequence is followed on the same page, and then repeated on the following page. For example, the first page is 1 snake, then you lift the flap and it shows two snakes and says 2 snakes. When you turn the page, it repeats the 2, then when you lift the flap it shows 3. And so on. I love that the sequence of the next number is immediate and then repeated on the following page. Great for learning minds!
