In seventh grade math the emphasis is on: (1) ratios & proportions, (2) rational and signed numbers, (3) linear equations, (4) scale drawings, area, surface area and volume, and (6) statistical thinking.

Math Galaxy’s Seventh Grade Math covers all of the Common Core math standards for seventh 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 are guided through problems step-by-step or can just give final answers.
Scores can be emailed to be printed.
Doing problems earns you robots for the Labyrinth, a maze search game.
Incorporates Schoolwork for classroom management.
