Trial and Improvement

Tomorrow I am about to start teaching Trial and Improvement to my Year 9 class and realised that I don’t have any fun resources on this topic.

I did a Google search and found a nice website outlining some lesson ideas.


Here is a link to a lovely spreadsheet simulation that gets the idea across pretty quickly and links to this starter problem. Click on the image to take you to the online simulation.


Once your pupils are ok with this, you can play a class game where pupils win imaginary money for their estimates.

Click on the image below to take you to another interactive online game.


When they get really good, there is a more advanced version they can play.

Many thanks to Maths Online for providing these wonderful resources free of charge. We like that.

  1. I’m a secondary maths teacher and I’ve just made a game to practise trial and improvement with my class here:

    It hopefully makes the topic a little more fun!
