What You Need to Know to Prepare a Lesson

Before I prepare an activity or lesson for a class, I am always careful to ask the JTE for these points:

-What lesson number will the lesson target? (If the lesson will not target a particulary lesson in the textbook, is there some other reference that will help to indicate the to-date progression of the students’ studies? That is, what will be suitable vocabulary and grammar to include in the lesson?)
-What is an example of the target pattern to be studied? For example: Can you play tennis? Yes, I can. No, I can’t.
-Will the lesson be a new/introduction, practice, or review lesson? (This information will help determine the activity types and pattern- or meaning-focus, and overall diffultly of your lesson.)
