just a simple idea - maybe dd can count to 3 or 5 before putting up her hand. Gives the other kids time to show they know the answer (without the "knowitall" beating them) but also lets the teacher know she is following and potentially has the answer.
I like suevv's answer about the little and big questions though.
I think a chat with the teacher would be valuable, she might be able to come up with a strategy that works with everyone. I'm having a time with DD4 now who doesn't like to show she can do well at music and gym so she's missing out, I think we are making progress by just telling her that the teacher/coach isn't a mind reader and can't be expected to know dd is great at it.
