Five Fabulous Activities book campaign is at 125% of its goal. Thanks, math friends! Stretch: every $100, we'll donate a book to a math circle serving people underrepresented in STEM fields. Contribute before Saturday Feb 29! #mtbos #mathchat #fivefabmath kickstarter.com/projects/nat…

About a decade ago, I was obsessed with teaching the classic game, Nim. I wanted my students to discover the winning strategy themselves. It's now chap 3 in #FiveFabMath. Won't you reserve your copy today? #MathCircles #MathEnrichment kck.st/2uGbmSG

We made it! Thank you so much for your support and encouragement. Last night we made it to 100%, and we're still going strong. Can you help us get to 125%? That's when we'll start unlocking our stretch goals. Please support, please share. #FiveFabMath kck.st/2uGbmSG
