Entry Events
Events that will be used to introduce the project to studentsTraffic Dilemma Challenge
A local traffic engineer presents a 'real-world' traffic dilemma (e.g., pedestrian safety near the school) and challenges students to analyze the situation using math skills and propose solutions. This includes a 'before' and 'after' simulation of traffic flow.Portfolio Activities
