The Giving Tree by Shel Silverstein is a classic childrens' book about generosity, and unconditional love. The tree loves the little boy, and as he is growing up he needs more and more from the tree. The tree gives him all she can to make him happy. In the end, she runs out of things to give the boy, but her love for him lasts a lifetime.
Use in the classroom: I would read this in a small group with my ESL or ELL students. The students will be able to match the pictures with the words for a better understanding of the book.
