I wrote a blog post about this exact same thing this week! And, I had this same realization while working on ratio, proportion, and percent problems with my Algebra 1 kids! Except, I haven't been encouraging my students to draw the diagrams enough. Instead, I've been drawing the diagram and cheating us both out of a learning experience. I need to keep drawing diagrams. But, I need to make my students draw their diagrams before they see mine. Then, we need to compare and contrast the diagrams to see what we can learn from each other!

Drawing diagrams is a tool for thinking and has the added benefit of revealing students' thinking to their teachers. I believe that teachers should be spending more time discussing and modelling the use of diagrams to help kids draw more efficient ones - ones that eliminate unnecessary detail and reveal the mathematical structure of a problem. Having drawn a diagram, students need then to be able to recognise the mathematical procedures required to solve the problem.
