Here's my day:
6-6:30 (depends how tired I am or whether it's a hair washing day) - get up, shower, breakfast, gradually wake up in front of the computer. Currently eating porridge whilst checking facebook and stuff, then will look through my lessons for the day and make sure I've uploaded key resources for pupils to access on their iPads or printed any sheets I need.
7:40-8 - leave the house. It takes me 20 minutes. On your PGCE placements it may well be much longer, but once I got a permanent job I chose where to live based on that. So I'm well out of catchment but have a simple drive with barely any traffic to get to school.
8am-8:20 - arrive at school. Get laptop set up, tidy anything in the classroom I left yesterday, photocopy any sheets needed. If I'm early enough, might get a bit of marking done.
8:45 - briefing (whole staff/department)
2 lessons, break (in my first year I was too busy, but this year I've made it to the staff room every day so far for a cup of tea).
2 lessons, then the start of lunch is generally spent dealing with pupils who have detention/are bringing me late homework, etc. I also do one intervention session for KS4 on a lunchtime.
Registration/assembly, then 2 more lessons.
3:30pm - At least one day per week I try to get away early (very occasionally home for 4), but I sometimes have to go to after-school detentions to speak to kids I've kicked out of lessons for behaviour. Most days I stay for a while doing work, marking books etc. (but tend to get sidetracked by chatting to colleages) and leave school between 4:30 and 5:30. I also have to do one after-school intervention session for Y11 per week.
Get home between 4 and 6 - have a bit of a break (tea and a snack, procrastinating on the internet) then plan a couple of lessons, then make and eat dinner, then usually do a bit more work (depending how much I got done at the weekend and how late it is).
10-11 - Bed.
And repeat...
At the weekend I normally take Friday evenings off and pretty much all day Saturday (I sometimes sketch out a vague plan for the week on scrap paper, so I can get straight down to making resources on Sunday). I work all day Sunday to try and get as much of the week's planning done as possible.
