This Application Problem is a part of the Lesson 8, Unit 4, Grade 4. Draw a series of clocks that show 12:00, 3:00, 6:00, and 9:00. Use an arc to identify an angle and estimate the angle created by both hands on the clock. This Application Problem reviews the sketching of angles from Lesson 7 and leads up to the Concept Development of today's lesson, where students further explore angle measure on a circle.
