Hamilton Trust
Started as open and is now a subscription model. Lesson/term plans and resources based on the UK Curriculum.

This is more teacher centered than for students.
This is one way of doing it - It seems to be used right through the UK - these are great resources that are peer reviewed and relate directly to their national curriculum. The resources I have used from this site as an Australian teacher have saved me hours of work. Most of the resources are not for technology enabled classes.
I would prefer that the content was more open, but the fee/membership is minimal for high quality material.
