Product Information Astro Algebra teaches the concepts and problem-solving skills necessary to learn basic algebra. Students learn how to graph functions, translate word problems into solvable equations, and represent algebraic expressions using the program's Virtual Manipulatives. Hundreds of problems in over 90 space missions provide students with a solid foundation for success in algebra and beyond. Special features include two learning modes, which allow for directed and independent learning and strong support of NCTM standards. Skills Learned •Solving for Variables •Expressions, Equations & Inequalities •Functions •Graphing on Number Line & Coordinate Grid •Ratios and Proportions •Slope & Intercept •Fractions, Decimals and Percents •Exponents •Problem Solving and Reasoning •Algebra Terminology and Notation Product 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 in order 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.
