Creativity with Desmos

Task: collect as many blue dots as possible, as few reds as possible.


Learning: inequalities in the plane.

Outcomes were very surprising. The assumption was that students would fiddle around with straight lines. Instead, they leapt ahead to bizarre curves, often using trial-and-error, and the power of online graph-sketching.

What even is this!?
Some great transformation of functions
The equation of an ellipse has never been taught…
Successfully turned the task into something very boring and easy. (Again, the student had only ever seen circles centred at the origin before)
  • Is it okay that these curves would never have been dreamt up if the students didn’t have access to technology?
  • Would there have been more profitable learning if I had restricted the game to straight lines?
