Year 10 trigonometry: Crossing the centre line

Updated 2023

Crossing the centre line is a series of trigonometry investigations aimed at Year 10 students. The context is set around driver distractions or micro-sleeps (or zoning out) when driving.

Students look at how factors such as differing speeds or distraction times affect the distance travelled towards the centre line if the car starts to veer towards the right at a small angle.

Includes lesson plans, unit outline, student worksheets and spreadsheet.
