1. Love this site. There are many levels and each time you get a correct answer the site donates ten grains of rice to the World Food Programme. Strengthen your vocabulary skills AND do something for others. Perfect. http://freerice.com/#/english-vocabulary/8099
2. This is a great free site for practice in both vocabulary and SAT prep: https://www.number2.com/about/index.cfm?s=sd1tYFLaSN8Zw5chNe8fErrf
3. Another free site- Word Dynamo- by dictionary.com: http://dynamo.dictionary.com/
4. Not a vocabulary site but a tool to help you see the words that are most used in a given text. "Wordle is a toy for generating “word clouds” from text that you provide." http://www.wordle.net/
5. Another fun tool to focus on the repetition of words in a text and its possible significance to the overall meaning: http://www.wordsift.com
