Reflection: Trust and Respect Working the Formula - Section 2: Put it into Action


The best part of this lesson was listening to the kids present their problems to their classmates and the questions and answers exchanged.  The team that presented the first question about contact lenses added an anecdote about one member who wore his contacts too long and had to leave them out for almost two weeks then start all over getting his eyes used to them.  It was interesting to watch his classmates listening with great attention as he and his partner explained their calculations and solutions to the problem, because I know they would not have been nearly so interested if I'd been the one explaining things.
