Given equal fractional parts of a circle (up to 8), find the measure of a central angle.

Clarifications:

Essential Understandings

Concrete:

  • Use manipulatives (pie shaped) to build a circle.
  • Use a protractor to measure the angle of each part.
  • Use a protractor to measure the central angle of the circle.
Representation:
  • Divide 360 by whole numbers up to 8 using tools, i.e., calculator, multiplication tables.

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.
