This is great website to browse in your spare time, maybe during summer break, to expand your thinking. TED.com's slogan is "ideas worth sharing" There's lots of different topics to choose from, and the people at these TED conferences are from all over the world so you really get a good perspective of global thinking.

This website was recommended to me by a friend who recently received her masters in education. She uses this website a lot because it has plenty of options to choose from. Activities, Coloring Pages, Flash Cards, and more.
