Sites for Teachers

A lot of teachers of EFL and not only worldwide look for sites and free online teaching resources and sometimes it is not quiet an easy task.
Here there are some sites that I have found and I considered to be useful. I really use these sites.

http://www.onestopenglish.com/
http://www.teachernet.gov.uk/teachingandlearning/resourcematerials/
http://free.ed.gov/
http://www.sitesforteachers.com/
http://teachingtreasures.com.au/
http://www.teachit.co.uk/
Personally I try to use the free printable worksheets as often as possible. Anyway one can easily find any resources they need or can him or herself upload and share materials on one of these websites.
