## Reflection: Intrinsic Motivation Organizing and Calculating Data with Matrices - Section 3: Exit Slip

In this sample of student work, the student presents two different ways to solve the problem on their own.  The student first shows a decrease of 35% on Sunday sales by multiplying .35 by the Sunday Matrix, and then subtracting it from the original matrix.  The student then shows a second method below by multiplying the Sunday Matrix by .65 to get the same answer.  This shows me that Common Core is changing the way our students think even without our request of them.  Students are starting to look for and see more than one way to solve problems.

Not all students take the extra initiative to show me more than one method, but the class culture is changing for more and more students to go above and beyond the minimum.  This kind of class culture rubs off on students who might of otherwise just sat back and not used their thinking skills to their highest potential.
