Today was a horrible day for me in connection with supply. It started out o.k. with the first lesson, but lessons following were bad. Period 2 I has 31 year 11s revising for an exam. They had not had a regular teacher for some time, but were the top set. It took me some time to get them settled and working but I managed to get all on task except for about 5. Some decided to throw glue around the room and just generally be annoying, but I suppose bearing in mind there were 31 of them and one of me, I didn't do too badly. Period 3 got worse. I can't go into detail since I don't want to be identified, but it was one of the worst classes I have had for some time. I only managed since the group was small. The last lesson of the day...well...it was also terrible. The work was not suitable and for various reasons this class hadn't had a regular teacher either, and they were all over the place. Some bright spots were that I did teach some great students who did behave and worked hard and I gave out a !of of praise and rewards. I feel so down....can someone give me a word of encouragement?
