Saw this tweet from Matt Henderson (via a Steven Strogatz retweet) today:
It first reminded me of one of Patrick Honner’s blog posts from a few years ago:
Honner’s post plus a lucky coincidence with a Numberphile video inspired a fun project with the boys:
It wasn’t until later in the day that a different thought about this graphic hit me – we did a project about this shape LAST WEEK!!
Since I was looking for a quick little something to do with the boys tonight, I head each one of them take a look at the tweet and tell me what they thought.
My younger son went first – he had lots of neat thoughts about the shape and we eventually found our way to the connection between this shape and writing 1/3 in binary:
My older son went next – he didn’t see the connection right away, but we eventually got there, too (oh, and ugh, just listening to this video I realize that I misunderstood my son when he was talking about a geometric series – whoops, he did say the right definition).
Thank you internet – what a fun coincidence!
