As a math teacher was searching for my daughter long after an exciting app for the Fire HDX under freetime. From Lillifee learning school for the Nintendo DS, we are both thrilled, This game has parts for tablet. Conni math motivated my daughter very much, she practices at the time + & - numbers up to 10 with the Abacus. Each badge motivate highly and are thus also the problem: When it reaches the badge in a light level and increases the difficulty level, the badge stand still and do not need to be re-earned! So she goes back to the easier task .... Dear developers: Please rework!
