This is great from @howiehua.bsky.social I have always called these "equation strips" but definitely love them for solving 1 and 2 step equations. Here are some resources I've put together

A vertical number line has natural intuition; the numbers are greater as you go up. Awesome for intro to negative numbers too.

I asked a student today which of these fractions was not equal to 1/2. He said, "It has to be one of those with a 3 on top--they can't both be 1/2" I'd never heard that before.

Her answer to 1/2 + 2/3 is unconventional but mathematically correct. Not sure what to do next. Maybe show her work to the class (with her permission) and ask for their feedback?
