The Desmos Graphing Calculator is a free tool that can be used on laptops, tablets and phones.
This 45-minute webinar was recorded as part of a series that looked at how the effective use of Desmos can help to deepen students’ understanding of topics in GCSE and A level Mathematics; in the case of this webinar, we looked specifically at geometry.
