Reflection: Connection to Prior Knowledge Ultramarathon Pacing and Rational Functions - Section 2: Explore


While working on the Ultramarathon task I heard many students talk about rational functions and make connections to the topic that they studied a little bit in Algebra 2. As I was going around one student who had the correct equation looked at me in frustration and said "I don't remember how to graph this." 

I didn't want to help the student right away, but I knew that he probably learned some "rules" for graphing rational functions in the past and knew that he could use them in this instance. To me, this was validation for using a context in order to introduce rational functions - the student did not remember the "rules," but I am positive that he could sketch the graph by thinking of Lily's average pace of her ultra marathon race.
