# Measuring and Naming Angles

Students learn about the different types of angles and how to measure them to within one degree.  As learning progresses they are challenged to measure and draw reflex angles using a 180° protractor.At the start of the lesson students investigate the perpendicular angles using a clock face.  In the main part they learn how to use a 180° protractor to measure acute, obtuse and reflex angles.  The end of lesson recaps students learning through a handout.
##### Differentiated Learning Objectives
• All students should be able to measure and draw an acute and obtuse angle to within 2°.
• Most students should be able to measure and draw an acute, obtuse and reflex angle to within 2°.
• Some students should be able to measure and draw an acute, obtuse and reflex angle to within 1°.
