Year 9 Mathematics - Angles and Gradients

Mrs Puzey year 9 math class was exploring the relationship between road grades and angles of elevation this week.

In class, students studied examples of road grade signs and determined the actual angle of a road given its grade. Road signs warn motorists about steep roads. A steep road has a high grade or gradient.

Then students constructed their own road signs using an actual angle of elevation.  Students then measured the gradient of ramps or stairs around the school.
