Narrative
Students spin a spinner to get a denominator for their target fraction. They choose a fraction less than one with that denominator and estimate an angle measurement that is the target fraction amount of 180. (For example, if a student gives a target fraction of ⅚, they estimate when they think the angle is 150 degrees.) Then students use a protractor to find the exact measurement.
