Here's a draft of a sequence of 6 tasks. Included in the speaker notes are sample hints/prompts to support/challenge/extend thinking, sample teacher moves and assessment considerations. Feedback always appreciated :) @pgliljedahl @MrValencia24 @KirstDy https://t.co/bZ1krAsz6z pic.twitter.com/B66qn3DivI

I tried this activity in @MsLyon16 's MTH1W class using Polypad on @MathigonOrg to help illustrate algebraic expressions. First Q: if this is x + 2 what would 3(x+2) look like? Students go to the VNPS to work in small groups: pic.twitter.com/H4EOyLnLvF
