Covers key math fundamentals

My kids (5&7) really enjoy the "sock game". We've only used the 1-6 and 1-10 levels but I like how the game ensures that they understand how numbers can be represented in various ways. I also like the option to play with hints or as a game of concentration.

My only idea for improvement is to allow players to determine how numbers are represented. For example, for the 1-6 level, allow a player to use any combination of numerals, words and dots. At first my son struggled with recognizing that "3" was equal to three dots. If I had been able to determine which way he was tested, I would have given this app five stars.

Great port

Glad to see this available here. My son has assignments to work on this site, glad to see the touch side getting some of the tools.

Finished or not I'm closing

This app is fun at first but it keeps shutting down after the first round. Very disgusting for a 3 year old.
