Primary Live Problems

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.

The last day for sending in solutions to our live problems is the 1st February.
