Cynical inner-city seventh graders are challenged by an odd idea from a math teacher. Frustrated that his students do not seem the least bit interested in learning, Mr. Collins proposes a contest to build the world’s largest tetrahedron. Several students show up for the first meeting, a few because they want to do something new. One picks math club over failing the class and another does not have anywhere else to go. Armed with reams of paper and glue sticks, the students begin building the huge structure piece by piece. However, the rainbow hued composition is not the only thing they are gluing together. As the weeks pass, they realize that they are forming something much more than a claim to a world record. They are building their lives. Recipes for barbeque sauce, cake and cornbread separate chapters, told in several alternating voices. Smart and fast-paced, this story inspires as well as entertains. (Fiction. 8-12)
