Morgan and Moffat Go to School — Tomie DePaola

Morgie and Moffie can't wait to start school!  They buy backpacks and pencil boxes, and off they go.  Moffie, who knows the answers to all of the teacher's questions, gets a lot of gold stars. And Morgie, who likes sharing his dinosaur book, makes two new friends. But by the end of the week Morgie and Moffie help each other to understand that it's important to both get gold stars and make new friends.  And they agree that they love school!
