Geometry contains many vocabulary terms used throughout the year. I print this packet on COLORED paper for the first introductory chapter as we reference it throughout the year. I focus on the pictures in this packet as I go through each term to express special markings, such as tick marks and arches. I also am very specific about notation as this will come up over and over again in proofs. It is a great resource to reference throughout the year. I will say to students, "If you forget, take out the yellow packet for reference!" No excuses!
