Day 7- Friday in Washington D.C.

Today, we used the MetroRail system as our source of transportation in Washington D.C. While waiting for our train to arrive, we stood outside of the Crystal City. As Mr. Ewalt explained how to use the ticket syste, I looked around to get a good view of D.C. It just so happened that we were standing on a tessellation. We were standing on bricks that were showing a tessellation using rotation. This was very helpful for the tessellation project we have to work on for math.
