Planning and organizing a group lesson is a necessary skill. Unfortunately too many tennis coaches fail to do this and end up giving a "wing it" lesson.
The best coaches have a written plan that they can bring out to the court with him to ensure a successful class.
Of course there may be times where you have to deviate from the lesson plan depending on what's happening on the court or how many people show up, but your goal should be to always have a written lesson plan for every group lesson that you teach.
We have found that using a lesson template makes lesson plan creation much easier. We have several proven lesson plan templates for you which can be seen in the next lesson.
