I found this free idea online years ago (https://algebrainiac.wordpress.com/2013/10/22/dance-dance-transversal/) and created my own slideshow presentation to play this game with my 8th Graders. They really enjoyed the game!
Short instructions are included at the beginning of the slideshow.
Before class, I use masking tape to create transversals intersecting parallel lines on the floor of my class. Another method (less noisy and less work) is to make the transversals on each desk and students can play with their fingers.
I usually pre-load the slideshow and find a song on YouTube or Spotify (some Earth Wind & Fire usually does the trick) and play that for the students through some speakers. I then use my arrow keys (left and right) to move back and forth through the slideshow to the rhythm of the song. I find that this is the best method because you are able to pick a song the students like, go through the slides at a speed that is good for your class, and ultimately control the entire experience.
