“My routines worked in September and slipped by November”

A routine is a habit, and habits are kept alive by attention. In September the routine was new. You taught it, watched it, and praised it every lesson, and it ran itself. So you stopped watching it, as anyone does with a solved problem. From there it slipped by degrees: one student a little slower, the chatter running a little longer, no single day looking worse than the one before. Nobody decided to stop. The class read where your attention went and relaxed along with it.

The drift is stable because there is never an obvious day to act on it. Each lapse feels too small to be worth a fuss, and by November content pressure makes practising how to enter a room feel like a step backwards. It is not. Routines decay in every classroom, and topping them up is ordinary maintenance. The techniques below do that maintenance from two directions: one treats the slipped routine as new material, to teach and practise until it is crisp again, and the others rebuild the attention that kept it sharp, scanning for slips early and naming the students who still do it well.
