three might have not been my ideal vision of a lesson I would teach‚ however‚ lesson two and four inspired me. Lesson two and four were interesting to me because I learned something new in each approach. I used my previous knowledge to solve a new problem. While lesson one was too boring for me to sit through‚ and lesson four was open-ended and I did not quite understand the point of the lesson. After we broke into groups and began discussing these lesson‚ I learned my two favorite lessons might

XYZ IB SL Math Circles Aim: The aim of this task is to investigate positions of points in intersecting circles. Introduction: The above diagram shows that distance r is the distance between any point‚ such as A‚ and the center of the circle‚ O‚ of the circle C1. The circle C2 has centre P and radius OP. A is one of the points of intersection of C1 and C2. Circle C3 has centre A‚ and radius r. The point P’ is the intersection of C3 with (OP). The r=1‚ OP=2‚ and P’=0.5. This is shown
