Even though we can't see the presentations, I think the summaries offer some good ideas. This one is my favourite: " Don't focus on getting info INTO students' brains, more on getting info OUT!". Check out the original post to see all of the 7 for 7 presentations at the TI conference.

Last not least @jgough Jill Gough: Visualization in a Language-Rich Mathematics Class Don't focus on getting info INTO students' brains, more on getting info OUT! What is the movie you are making in your mind? Verbalize/visuals for deep learning #T3Learns #T3IC #iTeachMath

Even though some of these are most certainly university level equations, there are definitely equations here that fit into the high school math (and physics) curriculum.

Here's a nice little applet to visualize normal vectorsIan Stewart shared what he calls '17 equations that changed the course of history' www.businessinsider.com/17-equations... ianstewartjoat.weebly.com/equations.html #mtbos #iteachmath #historyOfMath

I think this could be used when talking about number systems (in terms of triangle numbers) or to conceptualize the patterns that exist in (this particular) sequence.

This is a neat visualization that never occurred to me. Try it with your students1, 3, 6, 10, ... how can we find the 100th triangular number? pic.twitter.com/RUNgaC6iaV

I know these are simulations, but the math checks out and they would work IRL.Did you know we can visualize rewriting square roots? I wish I was at least shown this in school. pic.twitter.com/gnTrMGSxQz

This seems like the kind of question that has brute force solutions and more elegant solutions (and code based solutions). To me that makes it perfect for all grade levels.

Happy Monday! This problem is inspired by the 1971 Canadian Math Olympiad Q7 Which are there more of, 2-digit numbers that are divisible by their 10s digit, or 2-digit numbers that are divisible by their unit digit? #math #maths #ProblemSolving #iteachmath #mathsky
