There may be another way to look at it, with another answer. Now the student gives me their idea and, again, I don't say anything. I call it wait time two. Let's see if anybody else has an idea. So student answers the question, or has their idea how to solve the problem.
Teacher says nothing.
Instead he goes and looks at the problem. I wonder if that would work. And, again, it's a real uneasy time in the class. She came up with an answer different than mine. It gives them another opportunity to do some thinking.
