The Secret State is used as a redirection tool or a way for the teacher to get the class to get quiet. You can switch these out daily or use them weekly. Pick a "capital, state" card and post it to the board each day. Throughout the day, the teacher says the capital, "Helena" and they say "Montana" ...and get quiet. I find this to be a great tool to ensure my students memorize states and capitals as well as an efficient way to get control of the class.
