"I love to focus on how to make mathematical activities more congressive... so when I'm teaching art students I do a lot of activities where there is no right and wrong... [W]e're not trying to achieve an answer, we're trying to explore... [W]e build something. It's more craft-like. ...[M]aybe we're trying to build s, but it doesn't really matter if you didn't... [A]long the way we discover how triangles fit together and... how versatile an equilateral triangle is... and that you can make all sorts of shapes... and some... are Platonic solids... [E]veryone can explore... and... in the world of , this is... "low floor/high ceiling" activities where there's a very low floor to entry and a very high ceiling, so if someone really does want to go far they can, but... there's no real failure, because everyone has done something. ...[I]f we do more of that, then we will stop putting off congressive people from mathematics."
