Secondary Poster Problems for Summer 2020

We have a challenge a day for you throughout the summer break...

Each weekday from 20 July to 28 August, a new poster problem will appear on this page.

After you've had a go at the day's problem you can compare your approach to the solutions we have published, which are based on students' work. If you particularly enjoy one of the challenges and would like to explore further, you can follow the link to the original problem on which the poster is based.

You can find the Primary Poster Problems here.
