A Lot or a Little?
What you will—and won't—find in this app.
Kids can practice their addition skills by choosing different combinations of two addends that add up to a number requested by the game. Because Mathris is a work-against-time game, kids must practice working efficiently and handling the stress of the balls piling up as they are choosing and tapping balls that match. Mathris could become more effective for more kids if it included slower modes of play for kids who aren't ready for the level of speed at which it currently progresses. Still, this is a fun app that offers good practice in quick-thinking addition.
Ease of Play
Very easy to play. Simply look at the number you need to match and tap the balls with numbers on them that add up to that first number. It would be nice if there were a setting for younger kids to slow down the dropping balls or limit the range of numbers used.
Products & Purchases
After you play a few levels, it costs $.99 to unlock higher levels.
Parents Need to Know
Parents need to know that Mathris is a fun, arcade-style game kids can play to practice rapid-fire addition. Players tap on falling balls that add up to a target number in order to rack up enough points to move onto the next level before the screen fills up with balls. Mathris is OpenFeint enabled, but players don't have to participate in OpenFeint to play the game, and Common Sense Media doesn't recommend kids or tweens use OpenFeint without adult supervision (see Privacy & Safety concerns). Higher levels of play require an in-app purchase of $.99.
Is It Any Good?
Mathris can be the sort of high speed, in-the-zone, arcade-style fun that makes some kids forget they're actually practicing math. For other kids, though, it could be more frustrating than fun when the balls just keep coming, filling the screen full of more balls and more numbers, while they're still trying to figure out which ones combine to make the target number. It would be nice if the game had an "easy" or "slow" mode to adjust play for kids who aren't ready for that much rapid-fire addition. That said, this is a perfect game for kids who like speed and need addition practice.
Did we miss something on diversity?
Research shows a connection between kids' healthy self-esteem and positive portrayals in media. That's why we've added a new "Diverse Representations" section to our reviews that will be rolling out on an ongoing basis. You can help us help kids by suggesting a diversity update.
