TL:DR Here is a template to write lesson plans. Just make a copy to your google drive and fill in the blanks. Drop down menus provided are also customizeable.
Do you write your own lesson plans? At some point I was asked to write a lesson plan for the first time. And probably because I didn’t and don’t really teach off of already written lesson plans, I had no idea what a lesson plan would look like. I’m sure my first attempt was a mess. Just because you can do something well, doesn’t mean you can write a How To set of instructions to help someone else do it…

So as someone who occasionally has to help “train” ALTs, and I use the word “train” extremely loosely, this year I was flooded with lesson plans. I’ll be honest… I didn’t look past the basic design of any of them. My brain just shut off when I opened them all up, they were such a hodgepodge of different styles it made me cringe. But that’s not because they were written badly or by people who don’t know how to make lesson plans. I’m sure they were all wonderful… Just it’s hard to look at something and judge scores of them when all of them are all different looking. It’d be like having a dog competition, but your definition of dog is anything that has 4 legs and and fur.

So…. I made this: Lesson Plan Template
It’s a google sheet. There are 2 sheets included. The first sheet is the lesson plan template itself with some instructions on how to get started. The second is a ‘data validation sheet’ that also comes with instructions on how to use it.

I hope it proves helpful for when you want to make your own lesson plans in the future. I would suggest that my own company adopt a standardized procedure in the future, but my suggestions are received about as well as Firefly was by Fox executives.
