I love the DDR reference. Well done!

Thanks for sharing. I also added a techno soundtrack and we called it “Graph Graph Revolution”.

The best thing about this activity, exactly as you describe it, is that there are no numbers for principals or charter school executives to demand the kids use in a color-by-numbers fashion.

At the blog for which I write (www.mathnook.com/blog) we show how the higher brain can be liberated to think conceptually by making the number facts and other math bits that the student needs to get from concept to solution automatic. This exercise stands even our thinking on its head by stripping out the number component of a problem entirely, compelling a firm conceptual foundation before the “how-to’s” are introduced.

I have had the student play around with the system in their lab groups before starting the lab but this is a much better way to do it.

This is great. I have had the students play with the detectors before they started the lab within their lab groups, but I think doing this short intro as a whole group is a great way to start the activity.
