This book is great for showing that when you put your mind to something you can do anything. That having self talks with ourselves are healthy and very encouraging at times. This book shows that doubting yourself does not get you anywhere but confidence and perseverance does. I would use this in my classroom by giving them a train that has "I think I can..." and they will have to write things that they can do and are good at. After they write this they can draw themselves in the train and we will hang them on a track going up a hill and hang in the hallway. My classroom will be filled with encouraging words and positive thoughts. I think this book could be read with anyone but is mainly for the younger grades. The Lexile Level is AD740L.
