This activity introduces students to the graphing of polar curves. A few of my students made use of (played with) the polar-rectangular sketch while working on this activity. The first part of the activity, creating a dynamic value with a slider, is a repetition of the parametric activity that my students did, so the technicalities were streamlined. There is no sketch that goes with this activity, since the students construct all of it.
