I read the Grapefruit Lesson and thought it would be neat way to illustrate the idea that flat maps only approximate the way the world actually looks.
I wasn’t confident I could peel a grapefruit well enough to flatten it out into a “map” so I just took a little rectangular piece of paper on which I drew some continents and I asked Mackenzie to wrap my map around a tennis ball. She quickly ran into difficulty at the top and bottom, so we discussed how mapmakers try to account for that.
We then printed out a map (I think it was the one shown above), and I carefully cut it. Mackenzie and I worked together to fit it into a globe and tape it.
It’s a miracle our paper world survived, with Daniel’s curious hands nearby.
This appealed to my detail-oriented six year old and the lesson stuck with her. 🙂
