Lumosity

It's no wonder Lumosity is used by more than 25 million people. Its activities are comprehensive, and they make it simple to get started with a training program. Best of all, it's fun. The daily program lasts between 10 and 15 minutes, and it goes quickly when students are super-focused on the games (which all require some serious concentration). Kids will love watching their skills improve, and while the games feel almost as mindless as Candy Crush, they're anything but time wasters. Using Lumosity, students won't just be improving game scores; they'll also improve their brain function across the board, making things like homework and focusing in class a little easier.

With practice, students can improve speed, mental flexibility, and concentration. Once you start to see progress, it gets a little addictive, and kids will want to keep playing to beat their previous scores. Some games, like Lost in Migration, help with concentration and productivity over time. Others, like Familiar Faces, focus on memory. In this game, the user is a restaurant server who is challenged to remember customers' orders and names in order to get the best tip possible. Students also have the opportunity to explore the science behind the brain games. 

While they don't teach a specific subject, these mental workouts will keep the brain active and agile. Lumosity's games are colorful, well-designed, and challenging. If they stick with it, students will be excited to watch their skills improve over time.
