I'm desperately seeking mathy books. I am having very strong Math Thoughts these days. Math Parenting. Math Culture. MATH THOUGHTS.
I read through this to see if it would be appropriate for a pre-literate, semi-numerate preschooler. I think I saw somewhere it was more for elementary kids. Anyway, no. I think it's fine for a preschooler. The basic teaching here is PI. Pi is a thing. It's a magical number. Sort of. It's the measure of the circumference of a circle - any circle - if you multiply it by that circle's diameter. OK, now I'm never going to forget that formula.
I was amused by the names - which, obv, my kid will not at all notice as amusing. But PLEASE, you must call me Lady Di of Ameter from now on. It's a bit wordy in the middle. It feels a bit jumbled. The riddle is as opaque as the Sphinx. But the page with the various pies, wagon wheels, and other circles was clear enough.
Overall: I'm impressed. This one's a keeper. Now to see if my kid likes it.
