The “Scaling Shapes Activity and Lesson” is a lab simulation and lesson plan in which students explore changes in a geometric figure’s area and perimeter when scaled by given factors. It includes a student handout and teacher notes with a warm-up introduction, guided exploration, discussion, and summary. An annotated teacher lesson plan is also included with classroom teaching tips. The accompanying simulation can be found here: https://phet.colorado.edu/en/simulation/area-builder
