I just heard about this and have been researching it! Do you use it and what are your thoughts? Thanks.
Some elementary teachers in my district use it, but most middle and high school math teachers do not, so it can be a little hard for us to troubleshoot errors sometimes. When I demonstrate multiplication, for instance I don't have a calculator at hand, I stack, and I hope my students understand what I am doing. Calculators are pretty ubiquitous though, so I don't care much one way or the other.
Hey guys, it's not just for math. It's a way of teaching and it looks like a rubric for students to check off. I know we've all used rubrics, but this is a program for all subjects.
