Math Galaxy offers a series of software CDs that help students tie the abstract concepts of math to concrete experiences by using graphic illustrations at each step, which aids in retention. Students progress through the exercises at their own pace. According to the company website, this series is based on the following philosophy:

• New ideas must be connected to a child's current network of knowledge and experience.
• Skills develop along a concrete-to-abstract continuum, with advanced skills developed by generalizing from more concrete experiences.
• A child must see a wide range of instances of a concept in order to separate out extraneous material from what is essential.
• A child needs to be actively engaged with new ideas and not passively entertained.

This particular CD is suitable for 6th grade students. It has explanations, practice, and games covering decimals, ratios and proportions, percents, geometry, graphs, data analysis, and probability. Games included are Word Jumbles, Riddles, Bridge the Swamp, and Labyrinth mazes.

The on-screen explanations are clear, and the examples are easy to follow. If your 6th grader needs help in these areas, Math Galaxy is well worth a look.
