Explain '{{concept}}' to a {{audience}} three different ways: (1) an everyday analogy that is accurate about the key point (and state where the analogy breaks down); (2) a precise step-by-step explanation; (3) a fully worked example with each step justified. Then list the 4 misconceptions learners most often have and how to correct each, 5 practice questions of increasing difficulty with answers, and 3 questions I could ask to check real understanding rather than memorization.
