Objective: Identify and measure angles as turns and recognize them in various contexts.
The topic concludes in Lesson 8 with students further exploring angle measure as an amount of turning. This provides a link to Grade 3 work with fractions as students reason that a 1/4 turn is a right angle and measures 90°, a 1/2 turn measures 180°, and a 3/4 turn measures 270°. Students move forward to identify these angles in their environment.
