Geometry Solutions: Design and Play Mini-Golf
Students learn about geometric relationships by solving real mini putt examples on paper and then using putters and golf balls to experiment with the teacher’s pre-made mini put hole(s) framed by 2 x 4s, comparing their calculated (theoretical) results to real-world results. To “solve the holes,” they find the reflections of angles and then solve for those angles. They do this for 1-, 2- and 3-banked hole-in-one shots. Next, students apply their newly learned skills to design, solve and build their own mini putt holes, also made of 2 x 4s and steel corners.

Engineers solve geometry-based problems every day, and they use math and science to help them design and build many projects. As they work in their specific fields, engineers get to know the ins and outs of their disciplines in order to create the best design solutions. Often, the real-world implementation of designs and plans vary from the theoretical “on paper” calculations, so engineers always start with prototypes of their designs to test them, discover discrepancies, and then improve them and test again—a process called iteration.
After this activity, students should be able to:
- Use geometric tools, such as protractors and Miras, to measure and draw angles.
- Solve for unknown angles of triangles and reflections.
- Use geometry to solve mini putt examples.
- Apply geometry concepts and tools to design, solve and build their own mini putt courses.
