2nd gr. mathematicians worked together to estimate and count large collections with regrouping. They shared their strategies and critiqued the reasoning of others! Favorite kid quote, “That was mind blowing!” #RCSpride

Luke Grainger gives @WMUHockey their first ever NCAA Tournament victory on this wrap around. Levi was SO close from keeping this out of the net. But the Broncos are moving onto Sunday! #LetsRide

Love showing ideas like this to high school students and watch those that have always struggled with memorizing FINALLY understand what was going on in the problem.
No more memorizing "negative and negative give positive". The power/flexibility of zero pairs AND the understanding that (identical number) subtract (identical number) is ALWAYS zero.(ie. "I have no (-5)! Get some! Takes a while to sink in, but has tremendous power when it does:)

4 years ago I got a 0 on a quantum physics exam. i met with my professor fearing i needed to change my major & quit physics. today, i’m in a top tier astrophysics Ph.D program & published 2 papers. STEM is hard for everyone—grades don’t mean you’re not good enough to do it.

I used to burn toast 20 years ago. Now I am a pretty decent cook. I don't "average" my cooking abilities from my mistakes from the past. It is up to date. So should assessment/grading. If not, it's meaningless and worthy of irrelevance.
Kid scores 100% on a retest... Only given a 70%. For what possible justification do we put scores in the gradebook that do not match what a student knows? Here is some research for you "there is no average time to learn something" and each kid isn't the same so why act like it

My book now has a cover and a publication date! Aimed at the general public, it's an inclusive vision of what math is, who it's for, and why anyone should learn it. Coming Jan 7, 2020. @yalepress #iteachmath amzn.to/2FKE5Zd

I see this with a big robotics company in our area now. Makes changing K-12 math instruction that much more necessary @joboaler @ladams1rcs @Danielle_RDG1 @mrbyrdmath
