## Reflection: Unit Exams Final Exam Part 1: Open Response - Section 1: Final Exam Part 1: Open Response

At this point in the year, I was happy to see students adding lines to make sense of the problem.  There are certain problems on which students might opt out of showing work, not for lack of thinking about the problem, but because they do not always have the problem solving strategies to make sense of what is given to them.  There were some students who did not ultimately solve the problem correctly, but even they were able to show an understanding of key geometric ideas.  For example, some students drew the radii from points V, S, L, and N to the center of the circle as a way to look for congruent triangles and to establish some key relationships between corresponding sides.  On this particular problem, the most successful students found similar triangles and used inscribed angle relationships to solve.
