    I love this idea of teaching a concrete version of a task to drive a need for substitution or rather a use for an algebraic representation. Usually I start with an abstract procedure for how to evaluate an expression for different values using order of operations. There is no curiosity in that. I am looking forward to replacing this with concrete representations like this donut task.
