Topic B includes lessons 5-8. "Use a circular protractor to understand a 1-degree angle as 1/360 of a turn. Explore benchmark angles using the protractor. Use varied protractors to distinguish angle measure from length measurement. Measure and draw angles. Sketch given angle measures, and verify with a protractor. Identify and measure angles as turns and recognize them in various contexts." EngageNY (Currently, we do not have content for Lesson 6.)
