A great webpage explaining the basics of calculus with .gifs
The animations really add to conceptual understanding.
A lovely idea from Lesley Munro
Graphing Challenges is a lesson idea published on Desmos. The idea is simple: match the graph by drawing in an equation.
Mojulo is a slightly bizarre but intriguing ‘app’ (but entirely online) that animates any function you pump into it. Spend 5 minutes getting your head around it and it gets quite addictive.
