Math Attack Pro

Math Attack Pro empowers kids to increase basic calculation speed and, of course, accuracy. High-contrast blackboard-and-chalk graphics work well for older kids but don't leave younger ones behind. Plentiful controls keep kids in the driver's seat. An old-fashioned “ding” sound indicates correct answers, and the device gently vibrates with incorrect ones. Scoreloop and heyZap scoring networks may be motivators for teens with accounts (and permission to post to social media), but younger kids can content themselves with the basic and advanced stats kept by the app.

Kids should start in practice mode, slowly including more operators and increasing number of questions, then move on to timed or race mode. Survival, three strikes, and rounds modes should be saved to cement mastery. Kids can save their results, retry, or save to scoring networks (for ages 13 and up) at the end of each game. High scores for each game are available from the main menu, and unique usernames can be entered at the end of any game.

In practice mode, kids indicate number of questions and choose operators, powers, or "multipart" (two-step expressions with parentheses). Timed mode gives kids 30 seconds per expression; survival mode gives them 30 seconds for all 10 items in a quiz; race mode counts up the time to complete 25 or 50 items; and rounds mode ends if more than one answer is incorrect or time runs out. Each question page has one expression with four multiple-choice answers and information about progress, time, and score.
