Dan Meyer – 3 Act Math, Desmos, TED Talk and more!

On this episode of the Mr Barton Maths Podcast I got to speak to one of my all-time maths heroes, Dan Meyer.

Dan is know for many things, including his dy/dan blog, TED Talk “Math Class needs a Makeover“, 3 Act Math,, Graphing Stories, and now Desmos. He has also probably been the most influential person on my teaching career.

Great interview, I am also a fan of Dan’s pain/aspirin & three acts

Nice that the puzzle you shared can be solved, once the thinking has been done, using Desmos:
