Infinity Ring is a series of three free iPad apps from Scholastic. The app that I tried was Infinity Ring: Revenge of the Red Coats in which students travel back in time to the War of 1812. In the game students explore Washington D.C. and the White House. The primary mission that students have to complete is to convince Dolley Madison to leave the White House before it is burned. In addition to completing the primary mission of getting Dolley Madison out of the White House there are other mini challenges that get students to think about the War of 1812.
The Infinity Ring apps are based on The 39 Clues series of books.
