## Reflection: Modeling Introduction to Geometry (Part 2) - Section 4: Lesson Closing

The responses on the ticket out the door indicate that I have not used the words coplanar, collinear, and bisect enough - the students are still not feeling confident of these words.

Additionally, I have come to realize that the students think of our first construction as finding the midpoint of a line segment only; I have not made it clear enough that what we are also doing is constructing the perpendicular bisector.  I need to work on connecting these concepts better.
