I made it just under the wire. For a long time all I had were good intentions and a half-started slide deck, work on which always took a backseat to this and that. Finally, a few weeks ago I gave his classroom the presentation below.
It was a hit. YouTube has a lot of cachet with 10-year-olds. It helped that I made some of the presentation interactive; there was a novelty factor to having the class work out some simple but enormous numbers. They stayed engaged for the full forty-five minutes, volunteering answers, laughing in the right places, and asking smart questions.
At the end I distributed light-up YouTube yo-yos to everyone, which was an even bigger hit. Hopefully it cemented Jonah’s reputation as the coolest kid to know. But his classmates were into the talk even before they knew there was swag coming.
I invite you to reuse or repurpose the slides below. I plan to give the talk again in two years when Archer is in fifth grade, so any constructive feedback that I can incorporate before then would be welcome.
