Here are some of the activities for the Cambridge Maths Circle. The links are all to problems on the NRICH site that inspired the activities, so we hope that you might like to try some of them, and to explore the rest of the NRICH site.
If you'd like to discuss any of these activities with other Maths Circle participants and with our student volunteers, then you would be very welcome to visit Ask NRICH. We have set up a special thread for the Cambridge Maths Circle. To find it, go to the section called "Follow It Up" (you'll need to register to be able to see this), and then look for
the thread called "Cambridge Maths Circle". Registering for Ask NRICH is free and open to anyone. We hope to see you there!
To find out about future events, keep an eye on the MMP Events page.
The activities are arranged here roughly in order of increasing mathematical difficulty and knowledge required, but many of them can be tackled at lots of levels so could be almost anywhere in the list.
