Find the measure of a missing angle in a linear pair.
Clarifications:

Essential Understandings

Concrete:

  • Given a linear pair, measure each angle using a tool, i.e., protractor, virtual manipulative, etc.
  • Given a linear pair, measure the angle with the missing measurement, using a tool, i.e., protractor, virtual manipulative, etc.
  • Using a ruler, draw a linear pair. Label the measure of each angle using a protractor.
  • Use a transparency to trace the angle. Place the traced angle on top of the other angle to determine vertical angles.
Representation:
  • Given a triangle, subtract a number from 180 or 90 using tools, i.e., calculator, slide ruler, etc.
  • Given a triangle, subtract numbers using a table.
  • Given a triangle, subtract given angle measurements from 90 degrees or 180 degrees to determine the measure of the missing side.

    Table with 4 columns and 3 rows. First row is header row. From left to right: Labels are Angle Type, Angle A, Problem, and Angle B. Second row are Complementary, blank, 90 - Angle A, and blank. Third row are Supplementary, blank, 180 - Angle A, and blank.

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.
