In this two-player online game, students combine math skills and strategies to practice simplifying, converting, and multiplying decimals, percentages, and fractions. For each correct answer, the player places a colored ball on a 10-by-10 grid. The first person to place four balls of his or her color together in a row or diagonally wins. Students can choose different difficulty levels, response time limits, and types of questions. Problems range from simple calculations for reducing fractions to solving proportions. From the online game page, What, How, and Why buttons open sections that explain the activity's purpose, function, and where the mathematics fits into the curriculum. Supporting information includes links to related lessons and student discussion questions, which help determine what strategies the winning student used to arrive at the correct answers.
