Teammates tells the story of when Jackie Robinson became the first black Major League baseball player, and how Pee Wee Reese took a stand and proudly called Jackie his teammate. This book is best suited for 3rd-5th grades. The book would lend itself perfectly to lessons on nonfiction, as well as teaching about equality and standing up for what is right. I would read this book to the class the day following the fiction lesson using The Bat Boy and His Violin. The two books take place during the same time frame, and both are surrounded by the historical events of the time. This would make a great lesson in comparing and contrasting fiction and nonfiction.
