This is a Mimio Teach ink file. It can be used as a review game. Two teams of students choose coordinates from their opponents grid. They can reveal whether they hit or miss after they answer their question correctly. There are 28 questions that can be input.It works for all subject areas. My students really enjoyed this game. It can be used whether or not you have the equipment by simply downloading the software at http://www.mimio.com/en-NA.aspx under the Support tab in the download section.
