You are my go-to example when people complain about Twitter being a toxic place. Thank you for being you, and for all the maths, too.
Wtf! Have my masters in math. Been teaching for 16 years. Never knew this. You’re the best, howie!
@HDascheberg this was a strategy one of our 2nd graders “discovered”! Yup, works every time 🤩
As a junior school teacher for 29 years, I collect cool maths methods. I thought I had seen them all but a few weeks of following you has revealed many more which I have added to my collection!
Aw, thank you!
WTH Howie!? You mean I spent all that time carrying and borrowing for nothing?
These are great Howie. Please tell me you post somewhere else also, so I can watch these After Twitter
This. Changes. Everything!
This is super cool.... I'll practice this.
I have always shown this to my second graders. I require them to show proficiency in regrouping prior to n using it but they LOVE it. It breaks down barriers in math and makes children more flexible. Not all students are ready for it, but why deny those that are?
