What's New

Added optional animations for correct answers.

App Description

In eighth grade math the emphasis is on: (1) solving linear equations and systems of linear equations, (2) functions, and (3) geometric transforms, congruence, similarity and Pythagoras.

Math Galaxy’s Eighth Grade Math covers all of the Common Core math standards for eighth 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.
You can be guided through problems step-by-step or just give final answers.
Certificates with scores can be emailed from final-answer mode to be printed.
Topics covered are listed below along with their Common Core standard.
More details on common core standards can be found at: http://www.corestandards.org/Math/

Includes Schoolwork support for teachers with Apple School Manager and iOS 11.3 or later.
