Futaba!

Have you heard of Futaba yet?  Bizarre sounding name, I know, but it is the perfect app for the one iPad classroom.  It turns your ONE device into a game board for 2-4 players.  The device asks a question in its rotating center and the students race to respond correctly.  Win 3 rounds to get a futaba (which apparently is a little seed!?)

You have the option of using questions they supply (grade level k-5 specific) or your own.  You create a teacher username/password so it's easy to write and send out your own unique questions to one or as many iDevices as you want!  That means you can adapt it to any grade or subject and can even be used by the resource classes!

It's pretty pricey compared to some apps ($6.99). Luckily for you however, it is available through the Volume Purchase Program, which means I can buy it for you (OR, should we say, thanks to Ms. Hurst... we still have some $$ in our account from last year :)
Let me know if you're interested and how many iPads you have and I'll e-mail you the purchase code (once you "Redeem" this code, Futaba will automatically load on all of your devices).

Teacher Created Resources has some similar apps that turn your iDevice into a multiplayer game board.  These are geared toward 2-5 grades, but are more ELA based and the kids love them.  Check out this link to learn more: http://www.appannie.com/company/teacher-created-resources/ (those are available through the VPP as well :)
