## Reflection: Grappling with Complexity Matrix Transformations - Section 2: Discovery & Application

It may be sensible to allow students to use calculators to complete matrix multiplication during today's lesson.  For students who struggle with multi-step procedures, the detailed work of performing matrix multiplication by hand may inhibit their understanding of the concepts involved in transforming geometric figures in the plan.

For today’s lesson, it is more important that students know how the matrices affect the location and orientation of the image of a figure. I like to have students do a few by hand to see some of the patterns and how the zeros and negative ones affect the new values. However, it did get a bit tedious for most students, so I typically allow my students to use a calculator part way through.
