The little Engine that Could written by Watty Piper is a 3.5 on the Accelerated Reading leveling system. This story is about a train engine that is running smoothly on his track until he comes to a large hill. The train chants "I think I can" until he is able to cross over the summit. This is a perfect book for teaching persistence. It could be used to teach students to never give up and chase their dreams no matter how big or small.
