What could be more fun that having your monster be chased by three other monsters? Well that’s the theme of my latest math game.
Ziggy, Spot and Pete are the three monsters that you want to avoid. Harry is your monster and is controlled by tapping arrows on the iPad version or swiping the Siri Remote on the tvOS version. The tvOS version also supports the use of a game controller so Harry can be moved using a compatible gaming device.
The object of the game is to move Harry to the correct answer for a math problem shown at the bottom of the screen. Anytime that Ziggy, Spot or Pete run into Harry as they bounce around the screen, Harry loses a unit of energy. Fortunately when Harry gets an answer correct he gets a unit of energy back. The goal is to score ten points before running out of energy.
Teachers and parents will like the wide range of problems. Problems are randomly generated so the game is different every time it is played. Skills are organized and defined using the Common Core Standards. Look Out! Monsters! is a fastpaced game specifically designed to help kids get quicker at doing mental arithmetic. A limited number of free promotional codes are available by request. The app is offered exclusively by the iTunes App Store and sells for $0.99.
