SGCS has always been clever at using its space to full advantage.  

Mr Mattes and Mrs Ho, from our Senior School Mathematics Department were out early this week preparing a mathematical activity in the Junior School playground.  

Multi-coloured strings were pinned to the ground, crossing over from one point to the next, marking out unusual shapes. This activity formed part of a lesson on traverse and radical surveying. The topic is part of the Year 12 Standard 2 Mathematics course.

With the bell change, Year 12 students arrived and began to take measurements using tape measures, photos and compass Apps to obtain bearings.

They applied their knowledge of mathematical formulae including trigonometry to work out the area and perimeter of the surveyed shape. The students worked together with much enthusiasm.

A very clever way to teach mathematics.
