History: In the Summer of '22, I produced a “Fractle” every day for 90 days. I exploited the Wordle craze and invented fractles in order to provide a wonder-ful context for mathematical thinking and reasoning. 

All 90 fractles can be found in the Archive. I'm sharing My Solutions, too. 

I've published this collection of fractles in a pocket-sized paperback (and also in ebook)! Find 'em here. Check out that cover design by Keith Greenstein! I make about $1 on each one. I use these profits to buy copies and then I give them away.
