Number Explosion vs 4th Grade Math School Edition

A simple and fun way to practice your multiplication tables (1x-12x)! In this game you select a difficulty level that corresponds to the maximum Multiplier of random equations falling from the sky. Target an equation by entering its Product using the game's numeric key pad. If you are correct a missile will be launched which will explode the targeted equation upon impact earning you points equal to its Product. Any equation reaching your City below will cause you to lose points equal to that equation's Product. Equations moving horizontally test your skills by slightly exceeding the difficulty level you selected. Hitting these equations will earn you bonus points by exploding every other equation in the view.

In 4th grade math the emphasis is on multi-digit multiplication and division, developing an understanding of fractions and decimals, plus developing fluency in addition and subtraction. “These apps are a favorite in my house.” "I love all of the Math Galaxy apps for their ease of use."
