Sing along to this light-hearted romp while learning about different food chains within a single ecosystem. Which animals come out on top, and which animals end up as snacks? Hey Diddle Diddle teaches children about the food web, the circle of life, and the part that each living creature plays within an ecosystem. This book is so much fun, kids will have a hard time believing they’re actually learning. You’ll be singing Hey Diddle Diddle long after you close the book.
