One of the biggest complaints about similar triangles that I hear from students is that it’s hard to know what “strategy” to use to set up a proportion. This scavenger hunt is designed to help them figure out which strategies to use in any given problem.
There are 10 questions in this activity, including ...
Geometric mean in right triangles (3 questions)
Triangle-Angle-Bisector Theorem (2 questions)
Side Splitter Theorem (3 questions)
Overlapping triangles (that look like they will be Side Splitter questions) (2 questions)
I would recommend quickly reviewing these strategies before doing the activity, and asking students to think of how they know to use a specific strategy. For example, if they see an angle bisector, they should use the Triangle-Angle-Bisector Theorem.
Students can start at any station they want. No matter where they start, they should end up at the station where they started. If you are having students work by themselves, you might consider printing two copies of each station so students have room to spread out.
At the end of the activity, there is a quick reflection for students to do to help them determine the next steps they should take. This would be a great activity to do the day before the test because it should help them identify which types of problems they struggle with.
