A 180-minute two-lesson summative assessment for MYP Mathematics students applying trigonometry to a real-world accessibility problem. Students find a location with a step or level change, take on-site measurements, and design a wheelchair ramp compliant with EN 17210:2021. They produce a scaled drawing, complete five calculations (angle, slope length, gradient ratio, minimum run, rest landing), then evaluate accuracy, compliance, and real-world sense.
