What would be a good response to, A possible lesson that incorporates all four Cs of 21st-century learning in my high school math class is a group project where students model and analyze a real-world quadratic scenariosuch as the arc of a water fountain or the path of a thrown basketball. Students begin by collaborating in groups to choose a scenario and divide roles (Mac Iver et al., 2024). They collect data, use Desmos or graphing calculators to model the quadratic function, and solve for key features like the vertex and intercepts. Students are encouraged to think critically as they determine the most efficient methodfactoring, completing the square, or using the quadratic formulaand explain why it fits their problem. Throughout the project, they communicate their ideas with their group and give feedback on each other's reasoning. For the final product, students creatively present their findings through a slide deck or short video, integrating visuals and mathematical explanations. This lesson supports active engagement, builds digital fluency, and allows students to apply content in an authentic, student-centered way (Insititute of Education Sciences, 2025)
