Measure the circumference of a circle using string.

Clarifications:

Essential Understandings

Concrete:

  • Identify the radius and diameter of a circle.
  • Multiply decimals and whole numbers.
Representation:
  • Recognize the meaning of terms used in formulas as labeled representations related to circles.
  • Understand the following concepts and vocabulary: circumference, area, pi, and radius.

Number: MAFS.7.G.2.AP.4b Category: Access Points
Date Adopted or Revised: 07/14 Cluster: Solve real-life and mathematical problems involving angle measure, area, surface area, and volume. (Additional Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
