MathHappens participated in the playground where we had an opportunity to show our models, and debut the complete set of Tessellating pentagons as well as Penrose tiles.  In addition we offered a session on working with the museum community to combat math misery (presentation slides here), and build a sense of purpose and community in math class. And we moderated a round table on growth mindset, and provided some items for the raffle.   It was a  busy couple of days.  Thanks to Paola Garcia, Ben Duong, Payton Crawley and Michelle Tat.
