4.MD.C.6

Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.

Students will practice measuring and drawing angles \(\le 180^\circ\) using a protractor. Then students will learn how to measure and draw angles \(\le 360^\circ.\) Then students will learn how to classify angles as acute, right, obtuse, reflex, straight, and whole. Conclude this lesson by giving your students this challenge.

Note: The MAA lists the challenge as 7.G.B.5, but the challenge has nothing to do with angle relationships, so I've placed the challenge here, as I believe this is the right place for it.
