Building a distributive property expression with an @openmiddle theme. My hope is that this will actually help Ss remember to distribute in the future. Where would we NOT want to place certain digits? Why? 🤔 https://t.co/3m33zqFiIC @geogebra @robertkaplinsky #MTBoS #ITeachMath pic.twitter.com/KxGIBD3t0V

Re: order of operations, excited to be on an @openmiddle theme for my MS Ss. Feedback provided, yet they’ll still need to reason. Create TONS of versions by having Ss set their own goal value (lower left): https://t.co/p9EK6FjREB @geogebra #MTBoS #ITeachMath #math #RemoteLearning pic.twitter.com/Aai123c9EM

It's Pi Day on Sunday. Here are all of my PiDay resources. I am trying to suggest that The Rolling Stones are secret Pi lovers. Do you see it?

Getting kids talking is the focus of the book Five Practices for Orchestrating Productive Mathematics Discussions. It's a great book with a lot of great ideas. Extending some of those ideas is @GeoffKrall in this post. Check it out for more thoughts on expanding the conversation in your math class.

I think there is some great stuff on this YouTube channel (especially if you love Legos) but in this video they make a machine that creates a gearing ratio of 1 Googol:1. Before you get to it in the video, have your students figure out how long it will take for the last gear to rotate once.

One way to remember the digits of Pi is to make a poem with words with the same number of letters as the digits.
