Totally agree. You can literally teach students how to solve quadratics by completing the square by saying nothing and just listing a sequence of problems.

BTW, this book is amazing and well-researched. There's a TON of great physics examples in there as well. #physics #physicsed

Found a PERFECT Trigonometry problem while reading Project Hail Mary by @andyweirauthor I can't decide if I should have students just draw a picture and solve, or if I should see if they can find what is incorrect about the problem.. #mathed #mathchat docs.google.com/document/d/1bF…

Great conversation this morning about correlation vs causation. # of firefighters present at a fire is correlated with the amount of damage done... what can we conclude from that? Now, to figure out why gymnasts appear to be shrinking over time....#mathchat

Bringing the 'ole twitter account out of retirement to say this: I'm actually excited for this school year. It's going to be a good opportunity to innovate, encourage, and move out of our comfort zones. @JMSteeleAHS Can't wait to see my students!
