Kids love to play games that are fast-paced, quick-to-grasp, lively, and yes, competitive. We’ve captured all those traits, wrapped them into a simple concept and snuck in a healthy dose of learning – commonly used addition and subtraction facts.They’re all a blast to play over and over again and are much better alternative to flash cards. Each game features a set of problem and answer cards. Players need to be the first to match the correct answer card to the problem card that is turned over. To win, you must think quickly, match faster and capture as many card pairs as possible.
