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.

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?
