I was covering an upper primary class and doing some group work with the children when the TA comes in half way and completely takes over e.g. questioning the kids, asking for feedback, explaining tasks and plenary. TA then explains next task and what she expects of them(because I stupidly tell her) and I stand there gobsmacked and thinking I am a rubbish teacher over and over in my head. I know the TA is experienced in the year group and knows the children but it does nothing for my confidence! If it happens again do I say something or bite my tongue and just bank the money? Has never happened to me before.
