Sites that allow teachers to make their own educational games!

The approaching holidays are difficult for many of my students.  I notice that their attention wanders, their behavior unravels, and their capacity for learning new material decreased dramatically.  So, when I found this site, which will allow me to make educational games, I was very excited!  My kids used Sheppard Software earlier this year to learn their states, capitals and Canadian Provinces, and StudyStack.com to study for their recent Social Studies test.  Now, if they can play while learning their spelling, vocabulary, homonyms, heat and energy, ancient civilizations, or ecology, won't that be more fun!?

I'll let you know how it goes and post links on my portaportal.  If you try any sites, let me know too!

Happy holidays!
