Grade 7 Mathematics Module 3, Topic C, Lesson 16


Student Outcomes

  • Students develop the definition of circle using diameter and radius.
  • Students know that the distance around a circle is called the circumference and discover that the ratio of the circumference to the diameter of a circle is a special number called pi, written π.
  • Students know the formula for the circumference C of a circle of diameter d and radius r.  They use scale models to derive these formulas.
  • Students use 22/7 and 3.14 as estimates for π and informally show that π is slightly greater than 3.
