Club PenguinPanfuPoptropicaWizard101Moshi MonstersBinweevilsSTAY AWAY from Meez and Habbo Hotel. They are NOT suitable for children as the chat is not filtered.
Try Club Penguin. That's safe and suitable for kids that age range. It has a variety of parental controls and has a moderation team which accounts for the cyber safety of every player.
