All of the Above, by Shelley Pearsall (Little, Brown 2006)(ages 9-12):
Most of the teachers at Washington Middle School are ready to give up, including math teacher Mr. Collins. In desperation, he proposes that his students build the world's largest tetrahedron. Told in alternating points of view of four students, Mr. Collins, and one or two other adults, All of the Above offers a fun and heartwarming look at a group and community coming together for a cause. Plus, how can you not love a book that has barbecue recipes?
