Andrew is a passionate educator and inventor who relentlessly creates unique ways to spread a love of mathematics.

Andrew started his working life teaching in a variety of government and independent schools from Primary through to Tertiary. With ideas regularly keeping him awake until 5am he eventually stepped out of full time teaching to tackle the steep learning curve of becoming an entrepreneur.

Andrew’s desire to build skills and confidence in his students has seen him develop Think Square (a suite of hands-on maths games), Mirrogram (the world’s first reflective clothing line) and Skillhouettes (an app to track and record motor skill development).

His creative ideas have been featured on LightFM and The Age; he is a puzzle writer for COSMOS magazine and has been contracted to develop innovative solutions for Cricket Australia’s junior programs.

Andrew currently spends most of his time running student workshops and staff PD around the idea of ‘Intentional Fun’ where he takes great pleasure in demonstrating what a joyful, imaginative and playful pursuit maths can (and should) be. He is not afraid to think differently, make mistakes and try new things. Whether that’s playing tug-of-war to teach algebra or taking Year 12’s to every train station in Melbourne in 24 hours as a Networks problem.

Andrew will inspire you to see possibilities, be creative, and think outside the box as you shape the next generation of mathematicians.
