Help needed.

For my app inexperienced five year olds, this app is quite difficult to use. Especially when you first start nothing works. Otherwise the knowledge of numbers are placed ahead relatively quickly. The numbers are not well explained and trained in this game. Fast reached the app the level of first class.
Some exercises could not understand my daughter from the 2nd class readily itself. For example, the money management is practiced only in the middle of the second class.
