I'm thinking if I gave a pop quiz to my high school students with just a variety of clock faces (with hour and second hands) and asked them to write the time, too many (for comfort) would fail. I guess that would mean that even if just one failed that would be too sad for words. Anyway, I came across a picture in an educational book about teaching ideas, and it was probably meant for an elementary classroom, but I'm so going to steal it. The teacher took the little yellow stickies and just to the outside of every number put the correct minutes: 5, 10, 15, 20, ..., 50, 55. I'm thinking that I don't even have to do a lesson on it; it'll just be a silent lesson every time they look at the clock.***
My second idea came from the book, "Eat, Pray, Love". I want to make a poster of it. If I remember correctly, one of the author's friends in Italy said to her after she was berating herself for her language mistakes, "Be polite to yourself when you're learning something new." (or something to that effect). What a nice way to approach the scary waters of unknown math.
*** of course a former student just sent me e-mail about THIS clock, and I bought it, so who knows how good of a "time telling lesson" this will turn out to be.
*** and of course now that I look at each hour, there are 2 I DO NOT LIKE .... but maybe that will spark good discussion in class (cough cough)
