Recommended Outside Reading for Students The Great Number Rumble, by Cora Lee & Gillian O’Reilly, New York: Annick Press, 2007. When Jeremy’s school district decides to ban math because it is too hard, his best friend Sam takes on the challenge of convincing the school board, the town, and the students in his school that math is both necessary to everyday life and interesting. Higher level math concepts are touched upon, as well as biographies of famous mathematicians. Special features devoted to explaining tricky concepts or interesting tidbits are interspersed among the narrative.
