Measuring Angles Using Radians
In this lesson, the students will explore the radian as a unit of measure. They will estimate the measure in radians of arcs, and also help us think about the connection between radians and degrees.
Episode 1: Making Sense
The students investigate the radian as a unit of measure. They start by estimating the measure of two angles in radians.
Episode 2: Exploring
The students draw an angle that measures two radians.
Episode 3: Repeating Your Reasoning
The students continue exploring angles by measuring two angles in radians.
Episode 4: Reflecting
The students solidify how many radians are in various amounts of rotation and think about how that relates to degrees.
