I teach in a comprehensive, suburban, predominately white high school. My class is mostly 9th and 10th graders.
We had a difficult time defining “middle” for Challenge 4. Is it intended to be the average value of the highest and lowest cards in the set (with a bit of wiggle room for not having half-card values)? Or is it the median value of the cards in the set (with the knowledge that you would need to choose an odd number of cards?
I realize that I could choose one method or another, but given that some people have expressed that this challenge has created some frustration on the part of the students I was wondering if one is inherently easier to comprehend than the other.
I welcome any and all direction on this.
