Abstract	Middle school students need opportunities to craft informal mathematical arguments beyond justification of steps in an algorithm. Pentominoes provide an excellent vehicle for such activity. In this article, the authors describe an exploration with pentominoes that engaged a group of ninth-grade students in proportional reasoning, dilation, and spatial visualization while encouraging them to engage mathematical argumentation. (A bibliography is included.) (ERIC).
