Day 22 – Reflections deflected

I pulled out the Miras and was rolling through the lesson. Students were discovering how reflections worked and wrestling with the reflection over x=y.  The class in general was struggling the right amount on the right topic, until all of a sudden previous knowledge came up and bit me.  Little did I suspect they would have problems plotting points in the correct quadrant.  Out of all of the teacher moves I considered, I opted for comparing results to other students in their groups.  I ended with having all students write notes on the topic and compare to their partners.  I will have to continue the lesson another day to finish the transition from Mira to not.  I also have to remember that the lessons need one transformation per page.
