## Reflection: Problem-based Approaches Mean Absolute Deviation - Why be MAD? - Section 2: Explore

Okay, so mean absolute deviation is definitely in the 6th grade curriculum, however my students insisted they had never seen or heard of it!  It worked out fine since my lesson did sort of start from scratch, but I was a little bummed that none of the kids came to the table with any prior knowledge.  Perhaps it slipped through the cracks in our transition to common core...I am not sure!  The kids really loved the basketball problems with the two kids - where on paper the one child would look like a much better player, but in reality a coach would probably go for consistency - making the other child the best choice!

Hmmmm.....
Problem-based Approaches: Hmmmm.....
