I have a couple of friends who are getting their education degrees right now and one of them asked if I’d read any of these Sir Cumference books. I hadn’t, but now I have.
Sir Cumference and the Viking’s Map is a story that goes over the basics of the Cartesian plane. There are two kids who get a map that’s supposed to lead to treasure and they have to figure out how the coordinate system works, while being chased by enemies.
I like the concept but thought there weren’t enough plausible mistakes in it. They just read the clues and knew what the negative numbers meant and that you’re supposed to read the X axis first. There are probably sound pedagogical reasons for that, but it made it feel overly simplistic as a story. It felt too obviously like a lesson and not like a story you could happen to learn something from – for my taste at least.
Now I’m looking for more math/story books to see if I can find some I really like and will let you know if I find any.
