I will teaching Computer Science Discoveries and wanted to run through this free online course. I am enjoying it so far. I think for 8th graders, I would probably teach “repeats” (“loopy”) using a line dance such as the electric slide. I would ask the students to write down the steps to the electric slide. Then rewrite it using repeats. Then teach the class as a whole, getting everyone up and moving.
Then review the words iteration, repeats and loops.
