I would recommend A Pocket for Corduroy for kindergarten through second grade. For kindergarten the teacher will have to read it while for first and second grades can have it on their bookshelf. One lesson that you could do for kindergarten and first would be read the book and then give them a coloring sheet so they can color Corduroy. While they are coloring the teacher can ask questions. Another option could be for them to draw and color their favorite scene. For first and second you can also do an order of events chart together as a class or in groups. You could hand out strips of paper and they can put them in the order like the book or they can come up with their own events. This is also a great book book, because there is more than one book on Corduroy. Which means it can gain some enthusiastic readers.
