My 6yo LOVES Marble Math & so do I! Honestly, there arent enough words to say how wonderful this app really is! Not only have the developers made an app that is fun for the kiddos, but it reinforces + teaches them skills necessary for development. There is even an area where if the kiddo touches a certain object, the kiddo will then have ONLY a "flashlight view" of the playing board, which btw, is my sons fav!! In this mode, the kiddos must use their memory of the board in order to not land on incorrect answers. I love it because, especially w/ boys, it teaches them to SLOW DOWN & pay close attn to what they see & remember. My son would race thru everything IF he could!! Thank you SO much for this amazing game app!
