This game is amazing! If you like to play Scrabble and wish there was a math version, here it is. Students use the numbers and operations to create a number sentence. Instead of building on the words like in Scrabble, you build on the number sentences. Even though this is an iPhone app, you can enlarge the screen and it works perfectly on the iPad. The app prompts you to login with Facebook or e-mail, but is unnecessary. By selecting start a local game, students can play with classmates without providing personal information.
