Today more than 100 countries are uniting to honor educators for their tireless service. It’s World Teachers’ Day—an annual celebration started by UNESCO (the United Nations Educational, Scientific and Cultural Organization) to raise awareness for teachers and the vital role they play.

Join us in celebrating World Teachers’ Day by reflecting on the powerful effect teachers have had in your life. No doubt, you’ll soon be full of gratitude, but don’t keep it bottled up inside! Here are six ways to spread the love:

1.      Share it: Leave a comment on this post to describe and thank your most influential teacher.

2.      Tweet it: Use the #wtd2011 hashtag to honor a teacher or read other teacher-thanking tweets.

3.      Send it: Send a special teacher a free e-card created by UNESCO.

4.      View it: Browse an online photo gallery of gratitude or upload your own photo.

5.      Own it: Print and display the official World Teachers’ Day poster in your classroom or office.

6.      Remember it: Watch a special video tribute to teachers from the folks at Imagine Learning.
