I've just been prebooked at a school I've never been to, about 30 minutes away, to teach grade 7 math and French. I would never have taken the job, had I not gotten the call from a live person who had me recommended by a friend who was standing right there while the call was being made. Let's count the potential hazards, shall we? 1) It's teaching French, and I know not a whit. 2) It's teaching math, my very weakest subject (next to French, that is!) 3) It's teaching a grade I've only taught once before in my three years of subbing (and my strength is K-3!). The one saving grace is that there will be a student teacher. I'm hoping against hope that that person will be able to take on all the actual teaching. I'm just going to breathe through it and do my best ... there's nothing else to be done at this point.
