Mathematician, Musician, Speaker. https://www.bensparks.co.uk I regularly use Geogebra to present exciting/interesting mathematics, to help me explore my own mathematical work, and create useful teaching resources. I have a YouTube channel which includes a playlist of 'live geogebra builds'. https://www.youtube.com/SparksMaths I work as a freelancer, and for the University of Bath, and the Advanced Maths Support Programme, and help (with Tom Button) run the MEI Geogebra Institute in the UK.
