Find the area and perimeter of rectangles, triangles, and composite shapes by applying the correct formula. A parent or teacher gives 10 problems (at least 3 composite shapes) and checks that formulas are stated and applied correctly. The student should also be able to convert between units (cm to m, inches to feet).
Proof required
Submit a photo of 10 completed area and perimeter problems (at least 3 composite shapes) with the formula written and the calculation shown for each, and a parent or teacher note confirming the answers.
What gets checked
- Formula stated before calculation for each problem
- 8 of 10 problems correct with working shown
- At least 3 composite shapes decomposed correctly into rectangles and triangles
