Cute pictures!
Format: Paperback
This was a really cute book! I think this book could suit a variety of ages as it’s a cute little story but also sort of educational. The illustrations were cute! We will be keeping it in our winter book rotation

Every elementary teacher needs this book!!!
Every teacher needs this book. It's not just for young grades who are learning to count, but for older grades who are learning about organisms, habitats, and the animal kingdom!! It is so chalk full of information! The opportunities to use it in the classroom abound! The illustrations are amazing! The song is wonderful, and easy for children to learn, not to mention that it is a melody that many children already know. The best buy!
