Not a suggestion you may have thought of, but my daughter loved 2048 before she started school, and helps with numbers and multiplications. If a tablet, then 'mucho party' https://play.google.com/store/apps/details?id=air.com.globz.omgz&hl=en is a good game you both can play at the same time, again, my daughter loves this. Skiing yeti mountain: https://play.google.com/store/apps/details?id=com.featherweightgames.skiiing&hl=en is also a game she enjoyed, granted these arent kids games as such, but are good games my kid liked.
