A pool table has become the latest mathematical lesson tool for year 7 students at St Paul's Catholic College, Greystanes.
The students were asked to design a trick shot and calculate its angles over four weeks. They learnt geometry in the process.
Assistant maths co-ordinator Michael Dennis said the project-based unit was designed to fit with the new national curriculum.
"We asked ourselves 'what would be a great way to incorporate real-world situations with mathematics' and we thought about the pool table," he said.
"It's a brand new syllabus under the Australian curriculum.
"Students have got to ask more questions about the mathematics and there is more assessment for learning, rather than of learning."
Cameras and education-based social media site Edmodo joined protractors as tools to complete the task.
Jinil Patel posted early plans for his trick shot onto the site and used the feedback he received to perfect it.
"Jinil was one of the ones who experimented very early," Mr Dennis said.
"After a few days he was already practising on a table at home, doing some simulations to see what would and wouldn't work and posting it for people to see as well."
Jayden Roth said he and his classmates had equal time to test their trick shots on the school's pool table.
"Mine had three rebounds and it knocked a ball into one of the holes," he said.
"Using the reflection rule, the angle that the ball hits is the angle of where it will go."
