Optimizing Security Cameras can be used as a formative assessment task to build students conceptual understanding ratio reasoning to solve problems and solving real-world problems involving area. The security camera task requires students to make sense of problems while reasoning abstractly. Students use models and construct sight lines to determine which areas of the store are visible to the camera.

The task identifies potential student misconceptions and offers strategies to address student understanding.
