This school year I will be teaching four different courses – Geometry (2 sections), Discrete Math, Calculus Honors, AP Calculus BC. My Twitter feed is being bombed with first day plan posts, so I will jump in here as well. Sitting by a pool, so this I’ll not be lengthy.
Note that our first day has 25 minute classes and a long community gathering.
In Geometry I have started the past three years with a dramatic introduction to the handshake problem. It generates some fun guessing and conversations right off the bat. We are also able to revisit this problem in various forms during the year. I think it is a winning first day activity.
In our Calc Honors class I will take students out in the hallway with some wheels chairs. I will have a segment of hallway measured for length and we will have some races pushing these chairs down the hall. This, I hope, will generate some conversations about average speed tat we CAN calculate and all sorts of instantaneous information that we cannot. This should be a basis for distinguishing between secant and tangents over the first days/weeks of the course. Plus, it is fun to run down the hall!
In Discrete I am going to use a fantastic quote that I read this summer (you can find it here ) I think that this might generate some fun research and some fun conversations about magnitude.
In Calculus BC I want to start with a deep dive into a conversation about linearization and approximations. I have gathered some fun ideas on twitter about how this conversation can unfold. I hope it leads to quite a bit of noticing and wondering about accuracy and when/why that accuracy falls apart.
