Hi Jeff, I am enjoying reading through your lessons! I am teaching PreAlgebra for high schoolers for the first time and am really connecting with how you relate to the material. I am curious though - I have not read through all your lessons, but I see on your posters behind you "Attend to Precision", and, is it, "No Robots"? So what are the other posters you have? I assume it starts with a "P" and "L"? Anyway, I really appreciate you posting your content up here, thank you for sharing!
