What's The Percentage?

This is a very simple game that took me quite a long time to make; it would have been a lot easier if Microsoft Powerpoint had the ability to make an action button that takes you to a random slide.

Students simply guesstimate the percentage of the circle shaded, and then click to see the answer.  Click on a red, amber or green button to be taken to another question.

The idea is simply to give students an idea of what percentages look like.  I'll be playing it throwing a soft ball to whichever student I want to answer.  I may well throw in a timed element too - see how much they can score in 2 minutes.

I'm sure it would make a good starter for any class who respond to this sort of activity.

What's The Percentage?


  1. Powerpoint doesn't have a random slide button, but you can use a macro to jumble up a powerpoint! Instructions are here:

    It involves opening up visual basic (programming language), but is a lot easier than you might think.

  2. Ace, I will have a look at having a go at it. Thanks!


Please do make any suggestions for improvement, variations that could be made, and let me know of any errors in the resources, or sections that students find confusing.
