I've developed an android math game called MathLab that has started to gain popularity. It's a simple fill-in-the-grid puzzle with variable cell sizes and locking cells. My daughter's math teacher got very excited about it, so she asked me to add age/grade information to each difficulty setting so that she can recommend it to parents. I'd be very thankful to anyone who can provide me with that kind of rating info.
Also, does this seem suitable for the Google Play for Education program?
