Lesson Plan

What’s Your Angle?

Obtuse, acute, and right angles, oh my! In this hands-on lesson, students will learn about different kinds of angles through motion. Mastering this pre-geometry skill will help kids tackle advanced math as they get older.

Learning Objectives

  • Students will know what creates an angle and the different types of angles.


(10 minutes)
  • Introduce the concept of angles. Tell students that angles are made up of two rays with a common endpoint.
  • Create a chart of angles, including their measurements and drawings to illustrate their shape. This can be done on a whiteboard, projector, or using an interactive whiteboard. The should include right angles(90˚), obtuse angles(greater than 90˚), acute angles(less than 90˚), and straight angles(180˚).
  • This is will be the students' point of reference during the game.
