Features:

Play with the Basic Building Blocks of Algebra

You understand equations better when you can build them with VariaBlox. Manipulate the Blox to combine like terms, substitute or solve for a variable and multiply, and factor simple algebraic expressions. An alert warns you when your equation is out of balance!

Capture Satellites, Meteoroids, and Unusual Outer–Space Treasures

Drag objects into the Cargo Bay to sort them and solve a mathematical problem. Use the special sorting bins for translating between fractions, decimals, and percents and identifying equivalent rational numbers or exponential expressions. The Proportion Tool can help you solve scale factor, equivalent ratio, proportion, and percent problems.

Represent Multiple Points and Graphs of Linear Equations and Inequalities

Use the Grapher Station to solve problems and complete missions by identifying slopes and intercepts and solving systems of equations and inequalities. In some missions, a Number Line replaces the coordinate grid and you can graph fractions, decimals, expressions, and inequalities.

Special Features!

The math fun in Astro Algebra takes place in two modes, On–Duty Mode and Off–Duty Mode. You begin the program in On–Duty Mode, where you are directed through missions. You can also go into Off–Duty Mode at any time to freely explore the tools and stations at your own pace, view trophies, or play Equation of Mystery in the Cargo Bay. Surf the AstroNet, a simulated universe–wide Internet* that contains data on math topics and terms. Learn about important algebra concepts before or during a mission. Use the Calculator to evaluate functions, compute solutions, and create tables of values.

Astro Algebra’s Grow Slide

Automatically records your progress and adjusts to guide your learning. The activities in Astro Algebra offer dozens of math topics and hundreds of problems in 7th, 8th, and 9th grade algebra. As you learn and progress, the Grow Slide advances, offering more challenging problems. Students, parents, or teachers can also set the difficulty of each activity or choose a specific topic related to schoolwork.

*Note: The AstroNet is contained wholly within the Astro Algebra CD–ROM and is not connected to the Internet or World Wide Web. The Internet cannot be accessed through the AstroNet.
