My super simple 5 minute lesson plan which over the years I have developed so it has all the key elements, yet is simple to use and remember.
I set my objectives (smaller steps to main aim) and keep them to my elf at first, I then ask the class how we might break down the main aim into smaller steps, write these on the board. I then add my set objectives if the class does not think of them all.
I put an alarm on my phone which is fairly quiet when I should start my plenary which I prepare in advance.
I hand write mine, but I have also added it to a Word document, which you can add a text box to each section if you would prefer to type into.
Hope it helps :)
