Evidence Of Student Attainment:
Students:
  • Solve problems with the circumference and area of a circle.
Teacher Vocabulary:
  • Diameter
  • Radius
  • Circle
  • Area
  • Circumference
  • π
Knowledge:
Students know:
  • that the ratio of the circumference of a circle and its diameter is always π.
  • The formulas for area and circumference of a circle.
Skills:
Students are able to:
