This book is very similar to her popular The Mitten. The difference is mostly in the setting and the object all of the animals climb into. It is a perfect choice if you want to do a rain forest theme with your students or if you are talking about Costa Rica/Guatemala.
I will not be using my book until April, but I created my book companion in advanced as I knew I had to do some animal research. National Geographic and National Geographic for kids is a great resource for real pictures & facts about all of the animals featured in this book. If you would like to use it with your students, click of the link here. I hope you will enjoy.
