Because you can never have too much Twitter Math Camp here’s some more from Harvey Mudd College in Claremont, California…
The hit of TMC15 wasn’t a morning or afternoon session, it was a 10 minute “My Favorite” (you can hear more like this tonight by registering here). Heather Kohn presented her 3D design project where her students created some pretty awesome stuff using Desmos and 3D printing! Check out her blog post here. You can see more cool student creations like this impressive horse ranch...

Another fantastic session was led by Robert Kaplinsky about improving your questioning skills in order to better understand student mathematical thinking. Robert brings up the excellent point that just listening to your students is a powerful form of formative assessment. You can find his presentation and materials here. I plan to use this professional development activity with teachers at my school during our orientation this year. I’ll blog about it and let you know how it goes!
Lastly, because he won’t mention it himself, I will. Even though this didn’t happen at Twitter Math Camp, Andrew Stadel did lead three amazing sessions about a variety of ways to engage student’s thinking about number sense. Here is a video of Andrew’s edtalk at the California Teacher’s Summit. It’s worth a look!
