The teaching isn't so hard, it's the lesson planning that's the hard part!
I can come up with a lesson plan pretty quickly, thanks to my TESOL planning, but then I need another hour for all the copying, printing, formatting, etc. When I was in training, I couldn't wait to be independent so I wouldn't have to fill out that silly planning sheet each time and have the trainer check it. The joke's on me, though; my new employer wants me to email all my lesson plans to her at the end of each month. That means TYPING each one into a special form.
I visited another teaching location, and the teachers there have 3-4 classes a day, all the same level. That's one lesson plan a day. I have 4 classes, all different levels.
Being true to my tendency to make assignments harder than they are supposed to be, I just spent several hours editing all my September lesson plans so that they're in the right font, format, etc. And scanning all the worksheets.
I haven't even sent them out yet and it's already Oct.2nd. Sigh.
