    I am currently doing scale drawings with my seventh grade. We started by drawing a simple floor plan of a rectangular room to scale on a piece of gaph paper. The class was doing pretty well with finding unit rates and applying the equations to more generalized situations in previous problems dealing with proportions. (How many M&Ms in a given sized bag, how many grams of sugar in a soda bottle, etc.) But they’re having a difficult time seeing the scale factor as a unit rate in a drawing. To me, converting squares on the paper to correspond to real life feet or inches seems like an easy jump. Not so much for the students. Eventually students were able to accomplish the task, but not without a lot of coaching.

    I’m wondering how I could have stepped back from that task and eased them into it in a way that would have allowed more discovery.
