Still buzzing after last night but the school week was beginning to get to me. I think it's the frequent room changes. I (obviously) do not get my own classroom so not only do I have to prepare the lesson, I have to remember to take everything with me, find the classroom, get set up for a different space and then teach.
My 8.2.4 lesson was in another block and I got all the way there and realised I had forgotten their books. Panic. Fortunately, my colleague walked back to get them all and saved my bacon but a great example of the detail you have to remember.
