The NRICH Project "started in 1996 and is based in both the University of Cambridge's Faculty of Education and the Centre for Mathematical Sciences." One of the activities of the NRICH Project is "publishing free mathematics enrichment resources for pupils of all ages, including discussion forums and a mathematics thesaurus" online.
Knot 315
Mathematical Imagery by Jos Leys
Jos Leys has made use of mathematical ideas, such as Kleinian groups, to produce stunning images. One may view his beautiful work by browsing the various galleries on his site.
Knot 314
Visual Calculus
This site is a "collection of modules that can be used in the studying or teaching of calculus." Topics include pre-calculus, limits and continuity, derivatives, applications of differentiation, integration, applications of integration, and sequences and series.
