When we start with a question, that must mean there are answers to be found. Yes. Yes. Yes! And so we start with the creation of this Unit and it is not one of measurement but one to provide knowledge that will be measured...thus the rubric. Essential question? Aren't all questions essential? Well we tell our students, "there is no such thing as a dumb question." And yes it starts with the essential question. Perhaps we can equate the essential question to the essential vitamins...got to have them. Essential to life and essential to knowledge, or to the growth of knowledge in this Unit. "How did America's relationship with Western & Eastern Europe and China change because of the Cold War?"
