Mr. Wolf has just started teaching at Hazelwood Elementary. He wants the first day of school to go well, but he’s got his hands full with his new class of fourth graders. Some of his students include: Margot, who is new in town and is trying to make friends. Sampson, who brought something special to school for show-and-tell. Aziza, who just wants everyone to be quiet and do their work. And Penny, who is very sleepy because she has a new baby brother at home, goes missing! This delightful new series captures the everyday and unexpected ups and downs of a fourth-grade classroom.
