Moments in Mathematics
Junior School
Mathematical modelling of COVID outbreaks has been essential in determining the best courses of action to take during the pandemic. Our Year 8 STEM Mathematics students are using their knowledge of statistical analysis to advise State Premiers on the actions they should be taking. Below is an example of how the students were able to use mathematics to come up with informed decision about governmental policy.
Senior School
Our Year 10 students have recently completed studying the topic of trigonometry. This is a branch of mathematics that involves the sine, cosine and tangent of angles. These important ratios have been used extensively in the surveying and building industry. Their application is used to find the lengths and areas of all triangles, as well as in rangefinders and surveying equipment. Another important use of the trigonometry ratios is in using compass bearings to find distances, and in finding the height of very tall structures. In teaching this topic, teachers have placed a strong emphasis on students understanding the ratios and in applying them to a range of situations. This emphasis has included a strong focus on students thinking logically and displaying their thinking through structured setting out.
Family Fun
How did you go with the construction conundrums? The answers were “16” and “none because the barn is already built!”
As this edition brings us into the holidays, here is an idea for a fun – and delicious – family activity: pick a favourite recipe and get baking! Where is the mathematics you ask? Well, measurements and times are all concepts we work with in everyday life that also form foundational mathematical knowledge. Want to take it a step further? Try making a different amount of your recipe – double it, halve it, or try to make just one serve or only enough for one per person in your household (to do this simply divide all measurements in the original recipe by the original number of serves, and then multiply them by the number of people in your household). You can also explore converting units by changing between cups, grams, millilitres, etc., by using an online search for conversion rates, methods, and even calculators.
Happy baking everyone, and if you want to share your creations we would love to see them! Simply email a photo to
Have a safe and restful break.
