Reflection: Intrinsic Motivation More with Factoring Completely - Section 3: Closure

 

Exit tickets like this one seem to work well because they do allow students to take more ownership over the material.  Students like to make up their own questions or problems because it is more interesting.  This, coupled with the fact that the cognitive demand is higher will tie up the end of the lesson nicely.  

When my students worked on this, I could tell immediately who had a grasp on the three structures and who did not.  The majority of the students were able to come up with three expression that fit into each category.  The biggest challenge for the students were the trinomials.  Most students where able to come up with a trinomial expression, but only about half designed one that was factorable over the integers.  I received several answers like x^2 + 2x + 5 or x^2 - 3x + 8.  When I do this task again in the future, I am going to add that the expressions must be factorable in writing.  I verbally said this to the class but I felt that if it was in writing, more students would have payed attention to their expressions to make them factorable.
