Big Ideas: Angles are measured with reference to a circle. Angles are measured in units called degrees. A full circle has 360 degrees. A half circle has 180 degrees This lesson will build on students' knowledge of right, acute, obtuse and straight angles to introduce the concept of angle measurement using a circle. Students will explore the idea that angles are measured in degrees, that a full circle is comprised of 360 degrees, and a half circle is 180 degrees. Vocabulary: degree, circle, turn
