Mystery Math Museum on the App Store on iTunes.
I had to break away from my Christmas holiday to post about this awesome app deal. Artgig makes some really cool math app for kids that are engaging without being tedious and involve interactive game play that just happens to include math practice. Mystery Math Museum is normally $2.99, but you can grab it absolutely free right now.
This is an award winning app that is a sequel to Mystery Math Town. The goal is the find the dragonflies while exploring the various museums which are maze-like. The app is quirky and visually engaging. I also like the fact that it can be used for multiple players with different skill levels which works great for families with multiple children. You can work on all four operations (addition, subtraction, multiplication and division).
Recommended for students working at grade 1 to 6 level of mathematics.
