Free Rice - This site provides a vocabulary development game, as well as many others, and your play will enable donations to be made to the World Food Programme.  There is no registration required.  http://freerice.com/#/english-vocabulary/13427

Typing Web - This site provides both guided typing instruction and games.  It is extraordinarily useful for students to master typing and either this or the TypingMaster program on the school website (under Woodbury Library) would be a good choice for spare time work.  This site is free but does require you to sign up.  I have found it fun to balance the lessons with the games. http://www.typingweb.com

The following are articles that I found interesting and you may, too.
