I'm currently student teaching. I'm wondering about how teachers typically do content planning. My cooperating teacher (CT) often doesn't know what she wants to do each day. It is always changing, and I find myself in a whole new plan (if she discusses one with me ahead of time). Suddenly, I may be handed something to do that I didn't even get to look at before teaching it. Am I supposed to just start planning lessons with no guidance? I'm not understanding how it all fits together, how I should be deciding what to teach, for how long, and progressions. I'm supposed to take over very soon, but my CT has not answered questions about how she plans content.
