So this year, I asked to teach Geometry. I have 5 sections all Geometry to 4 different populations: honors, prep, regular and 15:1. Today was the first day that each population had a different lesson. This is clearly no fun and not recommended. Typically, I have been reviewing the success of my honors class on the blog because it has been a clear run at a lesson. Usually, this is the first time I taught the lesson. Because I am the Math Team Lead and have to meet with all team leaders during my class time on Mondays, I have to give a lesson that students can run by themselves. Everyone has their challenges, and mine come with working with a great group of teachers and administrators, so I gladly take them…
On Mondays, I will be picking the next best lesson for the day. I will typically pick the one from the regular class because it is in the stream of the whole year Geometry class. Today, I started teaching logic and really wanted to use the prisoner’s dilemma. Little did I understand that it would take all of the period to get through truth value and negation. There was no time for compound sentences. One tactic that I did for the first time was, after I had students in their notebooks their definition of a topic, I had them compare all of their definitions. This prompted a lot of changes and discussion. I will definitely do that again. Other than that change, I had a quirk in the negation of one of the sentences that made it more difficult. I am reluctant to remove the quirk because it paints a real picture of what could be. I was not surprised when students gave examples of truth value with only true statements. I will have to watch out for that in the future.
