Learning Goals
Students will be able to identify and evaluate limits from graphs, tables, and equations in traffic flow and signal timing models to determine whether a function approaches a value.
Students will be able to analyze one-sided limits in traffic flow and signal timing situations to explain when left-hand and right-hand behavior agree or differ.
Students will be able to classify discontinuities in traffic flow and signal timing models to justify how jumps, holes, and asymptotes affect the meaning of the model.
Students will be able to test simple limit cases for traffic flow and signal timing expressions to decide whether a model makes sense in context.
Students will be able to construct a CER-style argument about a traffic flow or signal timing model to defend a claim with evidence, reasoning, and a fair counterargument.
Students will be able to revise mathematical explanations of limits using peer feedback to improve precision, clarity, and use of evidence.
Students will be able to collaborate in a team to synthesize individual analyses into a public defense of a traffic flow or signal timing model.
Products
Individual Limits Argument Portfolio with Annotated Model Card and Audio Defense
Each student creates a portfolio showing independent mastery of limits in the traffic-flow context. It includes an evidence log, annotated graphs/equations, a claim with sub-claims, a counterargument and rebuttal, and a short audio defense.
Traffic Limits Showcase Panel Presentation with Collaborative Synthesis Board
Teams present a public defense of their chosen traffic or signal model using member contributions from individual research. They combine annotated visuals, a synthesis board comparing positions, and a live Q&A response to challenge and critique.
