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.
The last day for sending in solutions to these live problems is Monday 16 May. A new set of live problems will be published here before Thursday 26 May.
