A variation of the traditional pen-pals by mail can be found at www.epals.com. Here you can find a class among over 115 different countries with which to exchange information, i.e. e-mail letters. You can search the site to find a class with your interests that is in your grade level. This will most likely allow a steady exchange of letters and info and it's free! You may want to work this into the Writing Center so each week students may have a chance to respond to messages and write new ones after they finish their center work.
