Matthew Perez, the official timekeeper of Mrs. Mallory's third-grade class, has a special good-bye gift for her. The school year is coming to an end, and everyone at Albert E. Chapman Elementary School is counting down, including Mrs. Mallory's third grade class. In the last weeks of school there is much to be done, from putting away supplies to cleaning out desks to finding a summer home for the class pet, Rhoda. Now -- finally -- the last day is here! Matthew Perez, one of Mrs. Mallory's students, has a perfect good-bye gift for his teacher, and he can't wait to give it to her. But when is the right time? Not in the morning when other kids are giving their gifts. Not during the Last Day fun of kickball and ice-cream treats. Will Matt get his chance before the school day is over?
