Desmos Problems

Think FastFrom Desmos we have the outstanding graphing calculator, their Facebook page (you do not need to be a Facebook user to view this) is also worth keeping an eye on. Some of the photos available make ideal starters. See the Think Fast series or perhaps Mental Maths Monday; there are also several probability problems. I think I’ll try some of the Mental Maths Monday series with my sixth form students – look at this for example!

The problem shown in the image could be used with younger students but also with older students who could look at an algebraic proof.

Talking of problems, here’s a reminder of some of the great problems published in Numberplay in the New York Times, I do like this Coins in the Dark Puzzle!
