This video on the Royal Society for the encouragement of Arts, Manufactures and Commerce (RSA) website is an animated version of a speech by Sir Ken Robinson, in which he discusses the background to modern education systems and whether they meet the needs of a changing society.

A collection of interactive problem solving modules aimed at high achieving students in years 7 and 8 was added to the website last year. They can be found under activities for students in the High achieving students section or directly at: http://www.nzmaths.co.nz/problem-solving-modules

There are currently four modules available, with a further four being developed this year.  Each module explores a mathematical problem in some depth.
