Last quiz before the final on interior & exterior angles. Overwhelmingly, kids basically get the idea that the three angles of a triangle sum to 180, but the exterior angle thing is still eluding them. Suddenly, any three angles add up to 180, regardless of where they're located. Kind of like how every triangle is a 30/60/90 triangle, regardless of given information (like the question dictating that the triangle is in fact, isosceles).
After the quiz the students were given the schedule for the remaining days and instructed to begin creating a note sheet to be used on the final exam.
