With two weeks left, important to remember that to stop offering students new opportunities for learning high quality content because SBAC is over, validates the notion that schooling really is only about the test #notinmyclassroom

Hey #MTBoS - I authored a @TED_ED riddle! It's a wizard duel, and you need to strategize to maximize your chances to make it through. Could be good for classrooms working on #probability (just pause the video before the answer plays) #iteachmath youtube.com/watch?v=mmkCS5eA…

I saw this quote in a blog post from a Tweet, and now I can't find who wrote the blog. I tracked the quote down online. It was just what I needed today.

Students' number sense often declines when they are introduced to algorithms - they often become laser focused on those and stop making sense. Most algorithms are introduced way too early and they stop sense making. teapawt.net/MrTravisDrake/status/9…

When interviewing today, I asked a boy to figure out 50 - 35 in his head. He gave the correct answer of 15. His explanation: School starts at 7:50. It takes 35 minutes to drive and my Dad says we have to leave at 7:15. So the answer is 15.

There’s a fine line between a numerator and a denominator. Only a fraction of people will find this funny.

Interviewing students today. Here was one of the Foundations of Multiplication questions. Explanations were interesting, as always. I love this work.

Darn. Just learned on @NPRAskMeAnother that @MerriamWebster uses the exclusive definition of trapezoid. I am so on Team Inclusive. #MTBoS
