    Before I saw this video, I saw someone tweet about subtracting across zeros and how adding one/subtracting one worked. I shared it with my students and had them discuss to figure out if it always works and why. It was interesting to see who understood and who didn’t. My students who struggle with thinking in a variety of ways had a really hard time, but my students who think about math flexibly were able to explain it, test it out on different problems and share it with others.
