Materials

See attached lesson plan for complete list of materials.

  • scissors
  • protractors
  • Angle Sort worksheet
  • Two-Color Plates manipulative (students can make this easily)
  • Colored paper for Foldable

    See the attached lesson plan for detailed instructional procedures.
    Lesson Segment 1:

  • Guessing Game. Have students guess the geometric idea you are thinking of as you point to various real world examples of angles in the classroom

    • Lesson Segment 2:
  • Students sort and discuss angle cards
  • Sing angle song
  • Form attributes using Two-Color Plates manipulative

    • Lesson Segment 3:
  • Discuss and use angle measurement investigation worksheet to help students use a protractor
  • Create an angle classification foldable to record angle measures
  • Estimate angle measures using the Two-Color Plates manipulative

    • Practice
  • Assign virtual protractor from KidPort
  • Quiz
