I know I know...in other news, water is wet.

With that in mind, I bring you...Transformation Golf. The directions are "Get the blue shape to match the green shape." Shots are taken by commanding your dynamic geometry software to perform line reflections, transformations, rotations, and dilations on the blue shape. The early holes start with one-offs, and later holes require compositions of transformations. Accountability and notation practice come from having the students write down the specific transformation they used for each shot. There are deeper conversations to be had about how to decide par for particular holes, and for any hole. But, still, the beauty is in the undo button*.

I wrote this a few years ago, before I knew about Geogebra. So, the golf game file and the associated instructions use Geometer's Sketchpad. Perhaps some industrious soul will adapt it to Geogebra and share it with the rest of us.

I have an excel game file of Transformation Golf that is actually set up with flags, greens, a golf ball and hole on a coordinate grid. My students love playing it each year after we talk about rotations, translations and reflections!

ReplyDeleteI know I got the idea from something like that, but I don't know if it was Excel...it was maybe a flash game? This came out of wanting something similar but that would help them be able to visualize transforming polygons, instead of just coordinate points.

ReplyDeleteThis is excellent. I have sketchpad and am definitely going to use this. Thanks

ReplyDeleteWow! That is a super-awesome game! I am about to start the "slides, flips, and turns" unit with my students, and we will definitely be playing golf :)

That would be sweeeeeet! I hope you do. No pressure.
