#### MAT-03.MD.08

 MAT-03 Targeted Standards(MD) Domain: Measurement and DataCluster: Geometric measurement: recognize perimeter as an attribute of plane figures and distinguish between linear and area measures. MAT-03.MD.08 Solve real world and mathematical problems involving perimeters of polygons, including finding the perimeter given the side lengths, finding an unknown side length, and exhibiting rectangles with the same perimeter and different area or with the same area and different perimeters

## Student Learning Targets:

### Skills (Performance) Targets

• I can solve real-world problems involving perimeter and area.
• I can show examples of shapes that have the same perimeter and different areas or have the same area and different perimeters.
• I can find the perimeter of a rectangle when all side lengths are given.
• I can find the perimeter of a rectangle when some side lengths are missing.
