I created a cafe like board for math for my second graders. I played around on pinterest a lot and found a few but they were more management based and not strategy based. I wanted something that would complement my cafe board and voices board (for writing). For math I use "compute" (compute, organize, model, find a pattern, understand what's being asked, terms, and explain). After each whole group lesson I have my kids identify important vocab we used to put under terms and what strategies we used and what headings they should go under. It worked well for my second graders, but I'd like to find a shorter (but still math related) word to use!
