ExploreLearning.com This site is the one winning all the educational webbies for Maths and Physics. It clearly sees itself as a site providing resources for teachers/learners - and its full of the kind of resources that can only be provided on the web - i.e. animations or 'gizmos'. This is a commercial site, restricting free access to 1 gizmo a day. It makes use of 'ExploreMath' and 'ExplorePhysics' names.
