is there anything harder than teaching permutations and combinations? Of all the subjects and standards I get into, this is the toughest (for me.) After I go through the discussion about "does order matter" and work through some examples to help kids reason through the wording, I feel like I have "fired all my bullets" on this topic. Any hints? strategies? thoughts? If not, I'd settle for a good joke or story to make me laugh. regards.
