Remember these old-school puzzles? You scramble them and then have to move everything to one side to move another over till you get them all in order. This is what our periods feel like: we have to sometimes move everything over there to get that one thing–a lesson on, say, adjective clauses–over here.
It can drive you crazy. Thinking of it as a puzzle, some sort of intellectual, logistical game–how to actually teach writingreadingspeakingthinkingeverything in 40, 50, or 60 minutes.
This is the zen of teaching. Lean into it and laugh along the way.
