Big Idea: A protractor measures the circular arc of an angle in units called degrees. This lesson focuses on measuring angles in whole number degrees. Students practice first estimating, then using the protractor while discovering the attributes of various angles. The practice offered in this lesson will prepare students for measuring angles precisely and ultimately sketching angles. Students practice using mathematical tools and attending to precision, as well as making sense of problems and persevering in solving them. Vocabulary: Protractor, arc, ray, acute, obtuse, right Special Materials: Protractors
