Depending on the type of protractor students use to measure angles today, you may decide to move the location of this lesson. If students are using a 360° protractor, the lesson can be taught at this point in the unit (or even combined with Lesson 7, depending on block lengths and/or student readiness). If students are using a 180° protractor, you may decide to move this lesson until after Lesson 11, when students see that angles are additive, since the strategies for measuring an angle that is larger than 180° with a 180° protractor rely on this idea.
If you need to adapt or shorten this lesson for remote learning, we suggest prioritizing Anchor Task 1 (benefits from worked example). Find more guidance on adapting our math curriculum for remote learning here.
