Monster Math Duels is a new/free educational iOS app for Math. This fun app has students competing in class or at home on an iPad (split screen) or across multiple devices in different areas of Math (i.e. addition, subtraction, etc) grades K-5 (against each other or the computer). Monster Math is aligned to Common Core standards, tracks student progress, and is a great way to integrate Game Based Learning into the classroom.
