The hashtag #sidewalkmath has been used on Twitter for a few years as a way for teachers to share ways of bringing math into public spaces by chalking up sidewalks across the US. In these days of stay-at-home orders and flattening the curve, the hashtag has been a way for neighbors and communities to engage with each other through the joys of math. Even if you do not have a Twitter account, you can find inspiration here: #sidewalkmath. Let's get chalking, ANN!
