Books:Five Little Sharks Swimming in the Sea by Steve Metzger - Told in the style of 5 Little Monkeys
Shark in the Park by Nick Sharratt - A great interactive book. This book has it all, humor, cutouts, physical and verbal participation.
The Great White Man-Eating Shark by Margaret Mahy- A funny book, but long so use only with your pre-schoolers.
I'm a Shark by Bob Shea- I must say Bob Shea really is the best. This book is so funny and is easily one of my new favorites. It can work for pre-school, Kindergarten age kids as well and parents will appreciate the subtle humor. Two narrators so a great opportunity to do multiple voices while reading.
