  1. thanks, this makes a good follow-up video to when I usually try to at least begin to explain this concept at the high school level (setting up one-to-one correspondences from natural numbers to integers and fractions between 0 and 1) … I’ve even turned Cantor’s diagonalization argument into a game with some honors classes … they usually figure out it’s ‘rigged’ after a few turns

  2. Good visual for number correspondence to show to students. Students can try out the skill and then watch the video. If needed they may watch as many times as needed.

  3. This is a great way to show the concept of integers. I also liked the fact that the students can watch it over and over if they didn’t get the skill the first time.
