The Little Magician and the Big Bad Mark(1977)

Overview

Oliver is in the 4th grade. He hasn't been paying attention in magic class and gets a big, fat five on a test. He has to have the work signed by his parents, but he is ashamed and doesn't want to cause his parents any grief. So he tries to get rid of the five with magic or at least turn it into a three. He manages to create talking guinea pigs and singing geese, but the five remains. The other children are already angry with him because he has no time to play with all the magic exercises. And so he decides to confess his mishap to his parents. His mother shows him how he can turn the five into a better grade - and that has to do with learning.
