I like to call this activity Putt-Putt-Geometry. It is 9 glorious holes of trigonometry application! This works great as a Trig unit project, end of year project, or test review (maybe 1 or 2 holes for review). The students can work in groups, pairs, or individuals. If your students are not proficient with Trig, or you have not covered it yet, each hole can be done using the Pythagorean Theorem instead - simply tweak the directions a bit. I hope your students enjoy this as much as mine do!
