Ways of Thinking: Make Connections

Take notes about your classmates’ strategies for writing equations for the perimeter and area of geometric figures.


As your classmates present, ask questions such as:

  • How did you connect your expression to the figure?
  • How did you know that two expressions were equivalent?
  • How did you match the approaches of the three students to the expressions for the perimeter of the rectangle made up of 100 tiles?
  • What formulas did you use to find the perimeter and area of a figure?
