I have taken over a y10 class as one of our teachers has had to retire unexpectedly. It's a y10 class and it's science. I mostly get them last lesson and I have a plethora of issues. Mass refusal to listen, to open books or do anywork. 4 who do nothing and tell me they never do anything. Swearing, ripping pages out of the book, destroying work sheets etc. I have tried doing practicals but it's dangerous with them. I have done games, worksheets, board work, card sorts ordering games, fill in the blanks etc I know the last teacher was tired at the end and I want these children to get some success. What can I do next? How to get them on side.
