"5th Grade Math by Math Galaxy is a comprehensive review and practice app covering all of the basics for the grade level. This easy to navigate app offers kids a great way to get that extra little bit of help that they might need to solidify their understanding of basic math concepts."

"We have been able to find each and every math concept that we have been presented with this year outlined neatly within this app."

See the rest of the review at:

In fifth grade math the emphasis is on fractions, decimals and volume: (1) developing fluency with addition and subtraction of fractions and multiplication and division of fractions and whole numbers, (2) decimal operations to hundredths and whole number division with 2-digit divisors, and (3) volume.

Math Galaxy’s Fifth Grade Math covers all of the Common Core math standards for fifth grade as listed below.
The concepts are presented in bite-size pieces with an unlimited supply of practice problems, with numbers chosen randomly.
Illustrations are used throughout to reinforce the concepts.
By solving problems students earn robots to use in a maze game, plus there are several other games involving math practice.
Certificates and summaries of scores can be emailed to be printed.

Bad app

I Don’t recommend this app... it never works

Nice game for practicing math

Good game for improving your calculation and math skills, even gives some geometry theory. Some tasks are in a form of game where you can play with other player or with the computer. Every task allows you to earn points - robots, and then you can play a labyrinth game :) the only thing, it's really hard to tap using fingers.. As i saw they recommend stylus, but i think not everyone has it and maybe they should adapt it somehow for fatter fingers :) but my overall impression is really good, as this app is much better for kids than playing some angry birds!

Highly recommended

My son has become obviously better in fractions and volume after spending a few evening playing this app. It's fantastic! Thanks for this app, it's absolutely worth its money
