Reflection: Safety Daily Desmos and Factoring Day 2 of 2 - Section 1: "Double Root" Challenge


In this lesson, I allow students ample opportunity to try to graph the function on the opening slide and as a part of the conversation I asked my students to share their successes and frustrations with the activity.  Many students will respond that they were "Soooo close to finding the proper equation, but they just couldn't get the graph to turn back upwards instead of crossing the x-axis".

In all of this discussion, I made careful note to let the students know that I appreciate their willingness to share, especially if they didn't quite get the correct solution.  It is common for me to say the phrase "LOVE wrong answers!" once or twice every period. I do this because I want the students to know that we can learn so much more from wrong answers as opposed to only looking at correct ones.  Most of the time, I students organically to provide me with these, but sometimes I might lead them down the wrong road myself just to make a point!
