In this task, students are asked to interpret a mapping scenario and distinguish appropriate types of measurement strategies. In order to do this effectively, they must recognize that both shapes and angles need to be broken down into familiar pieces.
This assessment works well with students who have just learned about the Pythagorean Theorem and are familiar with area and circumference of circles. I have also used it in the introductory week of a high school geometry course. Students should already be familiar with:
- Area formulas for rectangles, triangles, and circles,
- Calculating perimeter and circumference,
- Composing common shapes to create irregular shapes,
- Properties of supplementary, complementary, acute, obtuse, and vertical angles.
- Pythagoren Theorem and its applications.
This task can be completed individually or cooperatively. It also works well as either an in-class assessment or a take-home assignment. I typically give students all three pages and review the tasks and rubric with them before letting them dive in.
