Day 145: Transforming Geometric Figures with Matrices!

Another tantalizing use of matrices.  On Tuesday (no class yesterday), my precalc kiddos used the TI Nspired Activity: Matrix Transformations to explore the effects of various matrices on polygons.

Using their experience, I asked the groups to determine the polygon matrix and then the transformation matrices for various situations.  We looked at the graph and the point-rule to deepen their grasp of how to determine the transformation matrix.  By hand we cranked out the elements of the resulting matrix to see what was really happening.

Once we debriefed and analyzed HOW the transformation matrices actually worked and WHY they worked (via point-rules), they began a second Nspire Activity: Linear Transformations.
