Each time you visit the NRICH site there will be some activities which are 'live'. That means we are inviting you to send us your solutions and we will publish a selection of them, along with your name and your school's name. If you'd like to know more about what we're looking for, read this short article.
You will find more live problems here at the beginning of September. In the meantime, why not take a look at our primary summer challenges? Every weekday from 19 July to 31 August, we will publish a new game or puzzle for you to enjoy.
