Math Galaxy Decimals, Proportions, %, is like having an interactive textbook, with explanations, practice, and games that cover decimals, ratios and proportions, percents, measurement and data analysis, including length, area, volume, weight, graphs, frequency tables, mean (average) & median, stem-and-leaf plots, and box-and-whisker plots.
The concepts are presented in bite-size pieces with an unlimited number of practice problems, with numbers chosen randomly.
By solving problems students earn robots to use in a maze game called the Labyrinth.
