Educational games on Amazon Fire for 4yo?

[Teanocoffeethanks]

Im a bit frustrated that my Amazon Fire doesn't support some flash software for some educational sites. Anyway, are there any good educational games or websites that a 4yo could navigate on an Amazon Fire.

Teach your monster to read is on the amazon app store and is very very good.
