Mrs Ostrehan’s Lower 5th maths group got to grips with the new GCSE syllabus during an outdoor practical on trigonometry.

The classmates used clinometers and trundle wheels to find angles of elevation and distance between buildings around Gad’s grounds.

They then used trigonometry to calculate height when back in class.

Maths teacher and U5W form tutor Mrs Ostrehan said:  “Formulas always make more sense when you can see them actually working.

“The GCSE curriculum requires the application of maths in real-life situations and the students were able to test and prove theories while securing their knowledge of the topic.

“How many parents remember learning SOH CAH TOA by wrote?

“Our method has helped improve the students’ understanding and allow them to further progress in their studies.”
