Reflection: Flexibility System of Equations Day 1 of 2 - Section 2: Introduction to Systems


One of my favorite things about teaching is that even though I cover the same curriculum each year, my students are always different.  Each group has its own strengths and weaknesses.  This year, due to a whole myriad of reasons my students came to me with some holes in their knowledge.  A solid understanding of systems was one of these holes.  I had to add today’s lesson plus some extra practice to get my students where I wanted them.  The discussion on the strengths and weaknesses of the different methods of solving systems folded into this.  I did give the students some time to brainstorm with their partners as a certain number were ready to have some ideas and opinions.  I used the resulting class discussion to firm up the remaining students’ knowledge.  Here is a sample of some Student Notes from that class discussion.  It is our responsibility as teachers to diagnose this type of issue in our students and adjust our lessons accordingly.  Next year, I may have students that are more prepared and will need less time.  That is the fun of being a teacher, you never know what you are going to get.
