Primary Live Problems

Each time you visit the NRICH site there will be some activities which are 'live'. That means we are inviting you and your students to send us solutions and we will publish a selection of them, along with your students' names and school, in a few weeks' time. If you'd like to know more about what we're looking for, read this short article.

Please note that these activities will stop being live after Friday 13 July.
