Operation Math: Code Squad is a great app that will help students improve their math fact speed with up to four simultaneous users. Like Operation Math by the same manufacturer, students practice math facts with numbers 1-­20 for addition and subtraction and 1-­12 for multiplication and division. As a secret agent team working for Agent Prime, students work together to defeat Dr. Odd as they complete a mission consisting of five rounds for each single math operation or combination of math operations. Rounds become increasingly difficult as students have sixty seconds to correctly answer 7 problems in the first round to 23 problems in the fifth round. If students do not complete all problems within the allotted five minutes, the time bomb explodes and the words “Mission Failed” cover the screen. Therefore, this app may not be a good choice for students who have anxiety, low confidence in math or have slower processing speed. However, since students can play as a team, students may have a greater chance of success than in the Operation Math single player game and may not feel personally bad. Students can also play against each instead of as a team and track their results. This is a fun math app that provides plenty of practice and effectively encourages multi-­player gaming and cooperation. Note: This app was originally reviewed for iPhone/iPad.
