Perimeter of Complex Shapes

 

Students learn how to find the perimeter of 2D shapes.

Learning progresses from counting the distance around the edge to finding missing lengths of composite shapes.

Differentiated Learning Objectives
  • All students should be able to calculate the perimeter of a shape when all lengths are known.
  • Most students should be able to calculate the perimeter of a shape by calculating unknown lengths.
  • Some students should be able to write the perimeter of a shape as an algebraic expression.
