Hey, Little Ant is a great book that challenges readers to look at life from an insect's point of view. It is the perfect book for teaching empathy. It can be really difficult for young students to understand the concept of "standing in someone's shoes" and this book does a really good job of showing just what this means.

Connections:
I absolutely love the lesson that lunchbuddiesplus shared on her blog. She uses Hey, Little Ant to show the difference between a "thinking of you" person vs. a "just me" person.
You can also get some ideas from the Hey, Little Ant Teacher's Guide.
