MathGirl Number Garden is one of those apps I encountered first as the Lite version, then loved so much I had to pay for the full app. This is a counting app where you select the number corresponding to the quantity of items shown as fast as you can. You’ll be rewarded with stars, which you can then use to buy flowers and other items you can use to decorate your own garden!
There is so much joy inherent in this app, your daughter won’t even notice she’s learning math skills. Plus, you may find (as I did) that you keep coming back yourself to beat your last score! There are several levels that are appropriate for elementary school kids on up–it’s addictive and fun.
