Online graphing calculator and interactive maths tool. Lands in CT when students build live, manipulable visualisations of function families that paper cannot replicate.
Interactive Desmos visualisation responding to slider input
Each student builds an interactive Desmos graph that visualises a function family (e.g. quadratics y = ax^2 + bx + c). They add sliders for each coefficient, label what each slider changes about the graph, and write a 100-word commentary explaining how the family transforms. They publish the link to a class gallery.
