Are you searching for fun educational apps? Here are some of the best out there and the sites that recommended them:
ReadingResources.net
This is one of the sites I included on my 'Resources for Parents' page. In addition to all the other wonderful information they provide, they have a page that suggests apps that educators have reviewed. Prices range from free to a couple dollars. I have reviewed some of the free ones and agree wholeheartedly! I also like that they group the apps by subject: Letter Knowledge, Phonemic Awareness, Alphabetic Principle (Phonics) and Fluency.
