What is geometric PE? It’s a way of teaching angles using hand signals. It’s a geometry game the students
love. It’s a way to break up the doldrums of desk work with activity. Here’s how to play.
The game is structured the same as Simon Says, only the teacher is in the front, and the students have to show angles after the command “Teacher Says.” Lines are indicated by pointing the fingers. The pointed fingers mimic the arrows on lines. Line segments and points are indicated with fists. The fists mimic the dots for the points on line segments. These are the commands:
- Parallel lines: Both hands straight up in the air, fingers pointed.
- Intersecting lines: Arms crossed overhead, fingers pointed.
- Right angle: One arm pointing to the ceiling, other arm pointing out at shoulder height, fingers pointed.
- Obtuse angle: Keep one arm pointing to the ceiling, lower the other arm down by the hips.
- Acute angle: Keep one arm pointing to the ceiling, raise the other arm to about 30 degrees.
- Line segment: Both arms straight out with fists.
- Line: Both arms straight out with pointing fingers.
- Point: Both fists placed in front of the heart.
- Ray: One fist in front of the heart, one arm straight out with a pointing finger.
The teacher leads the class through the movements, slowly at first. The speed gets faster as fewer students remain in the game. Finally, go as fast as you can until one student remains.
Students love to play this game. They also gain a physical concept of the geometric vocabulary, and actually use the movements to help them during tests and assignments. Any time you can get students involved and active in their learning is productive.
