ESL Printables is a community for ESL teachers to find and share worksheets and lesson plans. I use the term community to describe ESL Printables because of its unique registration policy and use policies. To use ESL Printables you have to be a registered user. Registration is free, but to complete your registration you have to contribute a printable worksheet, lesson plan, or Powerpoint of your own. Every time someone downloads one of your submissions, you also earn points that you can use to download more materials.
