    • TI Connect, a connectivity cable and unit-to-unit cables
    • TI-Navigator "send to class" feature

During the Activity

Students will:

  • Find the perimeter and area of rectangles and triangles using graph paper and a graphing calculator.
  • Find the circumference and area of circles in terms of pi and using a graphing calculator.
  • Find the area of irregular shapes.
  • Estimate the perimeter and area of real-world objects.


  • Directions:
  • Distribute the student activity sheets.
  • Follow the procedures as outlined.
  • After the Activity
