An Andrew Stadel (@mr_stadel ) tweet on parallel number lines with one being numerical and the other algebraic got me thinking. “What if I combined proportional distances on number lines with algebraic clues or areas on @fractiontalk diagrams with algebraic clues?” I started playing with a few ideas. Seeing how too much information led to straight forward thinking, I wanted just enough to be doable but still ensure mathematical reasoning. Here is the first iteration awaiting testing with students. If you find it fits with your classes, please try them out. They might make good review of several concepts blended.
