What: Interactive Quiz Website
URL/Link: http://quizhub.com/quiz/quizhub.cfm
Cost: Free- Limited - School Site available
Why: Great for Summer
This is a great site. It is limited for the free portion with only a select amount of quizzes available. I still think it is a great resource for summer learning. You could have your own children use this site during the summer months to keep up on academics!
