Reflection: Intrinsic Motivation Transformations Review - Section 3: Review of Compositions - Matching Card Activity


When we finished this activity, I asked the students to look at their answer sheets to see if there were any patterns in their numerical answers.  It is always amazing to me to see how intrigued they are by patterns, and they came up with a lot of ways of looking at and relating the numbers.  (The answers are 5-8-3-6-1-4-7-2.) 

When the discussion seemed to be winding down, I asked them how the numbers on a clock work, and how this might relate to these answers.  With this prompt, they were able to reason that I was counting by 3's and "reset back to 1" each time I counted beyond 8.  I explained this is called "counting by 3 mod 8", and we worked out a few more examples in different mods.  I know it doesn't relate specifically to a geometry standard however it is important to model that mathematics conversation should not be confined to a "course name" and above all it's fun to see my students get excited about math!
