Several years ago someone introduced me to this TED talk called “A Performance of ‘Mathemagic.'” I want to leave it here for any teachers who may need a time filler after testing, an opener/closure to a lesson, or just the general public who want to be amazed. I could watch this over and over again…and teaching 6 classes a day for five years, I definitely have.
Side note- Arthur Benjamin came to Trinity a few years ago and knowing that he asks members of the audience to come up on stage and participate, I decided to bring my calculator and see if I got picked…I did!! That was a pretty awesome day! 🙂
