Students will launch the investigation by sorting real-world scenarios into plausible function families, testing initial classifications with graphical and contextual evidence, and revising their reasoning through peer critique.

Students will investigate competing function models for a real-world scenario, test them in Desmos, critique mathematical evidence, and revise a team model and individual portfolio entry before the showcase.

Students will defend a real-world function model with mathematical evidence, compare plausible alternatives, revise their work after feedback, and complete an individual portfolio reflection.
