I find that I refer to certain problem-solving strategies over and over again in my teaching, and it is useful to have these as a ready reference in my classroom as a wall display.
I have collected a variety of resources online to add visual stimuli to the basic ideas here, and hope others might find it useful.
The problem of how to share/print a display of 7′ by 3′ is interesting. Personally, I print it in sections, but I provide a single pdf as an idea of the display. I actually prepared it as a massive Google Slide.
