Curated OER
Area and Perimeter
Students explore area and perimeter. For this math lesson plan, students differentiate between area and perimeter and compute the area and perimeter of an object.
Curated OER
Perimeter All Around
Students explore perimeter and area of regular and irregular polygons. They experiment with color squares and create different arrangements using the same number squares. Then they compare the area and perimeter measurements of each.
