We have to really think about what does this mean in action? How does it look in the classroom? How do we get fluent as a teaching community ourselves, so that we can teach this way. I think one way to start is to have grade level discussions about how to operationalize this. I do think that we should use small guided math groups to discuss different strategies because you want to give the students a chance to talk about their thinking. Dr.
