Walk and Talk in time
If you are trying to remember the words alone for each element you will find it difficult, particularly applying them when you are flying.
Observe Sky divers, Aerobatic pilots they all do the same thing. They rehearse the moves on the ground and by doing so they relate the moves to their thought processes. An actor does exactly the same thing.
Fly the lesson sequence while on the ground. If you are worried that some will think you look like an idiot - go somewhere private. Think carefully what should be learnt from each move then add the words which will now come more easily. Of course it is important that all this is sycronised and that will require extensive practice and is perhaps for any instructor the most difficult part.
What is of utmost importantance to the student and also very important to you, as a rooky, is that you brief the flight on the board from you short brief crib exactly as you intend to conduct the flight. By doing so you not only brief the student but yourself as well.
