A pupil hears far more English from the teacher running the lesson than from the lesson content itself, but only if the lesson is actually run in English. For a teacher whose own English is still developing, that is a genuinely difficult step, and it usually fails when it is attempted all at once.
This resource lists the fifty phrases that do almost all the work of managing a class: giving instructions, organising groups, praising, correcting, managing time and closing a lesson. Each comes with a simple pronunciation guide, a note on when to use it, and the gesture that makes it comprehensible the first few times.
The four-week plan introduces roughly twelve phrases a week, in the order a lesson actually needs them. It is written for a teacher who is learning the phrases at the same time as the class, and it says so honestly: there is a section on what to do when you forget one mid-lesson.
