This has been around a while but I love this visual representation of the Pythagorean Theorem that emphasizes the area (or volume) of the squares outside the triangle and not just the length of the triangle's sides. #MTBoS #iteachmath

I absolutely love teaching at my school and love my students, but it needs to be said: teaching kids at low income/high needs school where so many have experienced trauma is tough. We have fewer resources each year. I am barely hanging on. Today was rough. 😔#teachertwitter

Place Value Multiplication for iPad, Windows 10 PC, and (soon) Chromebook
Esa Helttula retweeted
I'm comfortable giving the student who needed 4 attempts to master a skill the same grade as the student who only needed 1 attempt. 'If' a student learns is more important to me than 'when.'
