I have to share because this tool is just too cool! Check out Visuwords, an online graphical dictionary. Type in your own word or click on "random" to see the word connections explode on the screen. Be sure to check out the key that explains colors and symbols. It would be interesting to have students create their own word map in Word, Inspiration, Powerpoint or Bubbl.us using the symbols and then compare it to the results in Visuwords.
