Composition is hard for students—but the multiple representations shown in this webinar will get them over the rough spots and help them to generalize and master the concept of composition. We'll compose functions both geometrically and symbolically, find the links between different representations, and put the behavior of the variables front and center. We'll show, and make available to attendees, composition activities that are accessible to early-algebra middle-school students and activities that will give high school algebra and pre-calc students new insights. The function dance activities from this webinar (in which the dependent variable dances with the independent variable) are likely to become a favorite for students at all levels.
