Good Educational PC Games for 5-7 year olds? - educational pc games

I was expecting a 6 years from the first attempt in the next year and showed great interest in the team lately.
Can anyone recommend me some good educational games / programs for a first grader. I think something in the basic arithmetic, reading, etc. helps. If fun and take care of more than 6 years.
So you recommend some games or game series, so we can start as soon as possible. Tell me what you have tried and / or what you like Childs. Thanks
