Motivate (using video conferencing in Maths) http://motivate.maths.org/content/ MOTIVATE is a project incorporating a series of video-conferences, run by the Millennium Mathematics Project at Cambridge. Everyone interested is invited to join in. Learning about the mathematics and working on the problems posed on these pages does not depend on attending the conferences.
Read the articles which introduce and explain the mathematics needed to tackle the assignments. On each topic there are five different, but related, assignments. You do not need to attend the video-conference to be able to do the assignments. Many other young people from all over the world work on these assignments and often give presentations in their own schools in a similar way to the presentations given in the video-conferences. The main objective in giving the presentations is to explain the mathematics carefully and clearly so that other students the same age, who have not tackled the same assignment, can understand and so that everyone can have a discussion about the work.
