When Zachary forgets his homework assignment, readers will be amazed at what he is able to accomplish with what he finds in his pocket. Each week he takes on a different math concept (length, width, area, perimeter) with projects that include a mobius strip, a paper frame, and a light show. Instructions for doing Zach's projects are included at the end.When Zachary keeps forgetting his mathematics show-and-tell items, he thinks fast and teaches the class about perimeters and areas using ordinary objects like paper and a flashlight.
