It's a blessing and a curse
Blessing:
Different day every day
New start every day
Not taking work home
Less performance-related stress
Curse:
You are viewed as lesser
Kids therefore try it on more
You can be covering all the lessons all day/travelling/no respite
Poorly paid
There are also the usual paradoxes/mixed messages
Get an outcome in their book but don't spoon feed them
Encourage independent learning but do scaffold
Cajole/use humour/develop positive rapport but don't befriend
Supervise/coach but don't "teach" (union)
Deliver meaningful lessons/what the teacher would have done but don't worry, you're not a specialist
Do as I say but not what I would have done ("good class" "like quiet" "exam conditions" etc when you know they're not, they don't and they won't!
)
Low bar: Give out the instructions/don't let them kill each other
Medium bar: Help them learn/have an outcome you are proud of
High bar: Deliver the lesson/lesson objective met and tested
Low bar work: wordsearches, posters, mind maps, revision, educational colouring in, copying out
Medium bar: exam papers, gap-fills, textbook work
High bar: PowerPoints/higher questions/essays/GCSE original texts
Ironically, the most basic work - set as a non-brainer - can cause the most issues as it's not valued/it's basic or you don't have the right tools (posters but no colours for a whole class)
The lesson plans and resources aren't usually differentiated in any way
The "Turn to page..." is often dull as dishwater
The PowerPoints or higher-level work you may be well out your depth with
So...
You need to accept that your main duty is to create a learning environment where those that want to do well can, where the students feel safe, where they have met you halfway, where they have achieved something/written something down that was useful/will be useful in future.
It's a hard balancing act.
Good luck
