What do PE substitutes actually need included in the plan?
I think it is easy to write a sub plan that makes sense to us because we automatically fill in the missing details. We know where the equipment is, how students enter, which rules need to be repeated, and what to change when an activity is not working. A substitute knows none of that.
I try to include setup, safety expectations, transitions, equipment locations, and a simpler backup option. Those details are usually more useful than adding another paragraph describing the activity. What is something you always include in your sub plans because you learned the hard way that it matters?
