For an age of seven years old, after doing some research it looks like the best tablet for a child of that age would have to be a tablet from either VTech or LeapFrog. Those companies design tablets specifically for young children around that age group which would provide them the skills to be able to use and operate more advanced tablets, such as Android tablets or Apple iPads, when they get older.
Children's tablets are different from regular tablets in that they offer downloadable content specifically for kids. This includes games, books, and learning apps.
Learning tablets are available for kids of all ages now. For example the Leap Pad, which is a very popular tablet like device for younger children is recommended for age 3 and up.
The best online retailer for learning tablets is amazon. They have a vast number of tablets available from different brands. Prices range from 10 to 50 although cheaper and more expensive models are available.
I found the best advice at fun.familyeducation.com. They feature all the different tablets and have reviews for each on the educational value that your child can get from owning a tablet.
You don't mention the age of the child, but among the tablets you might want to consider are: InnoTab by V-Tech, LeapPad by LeapFrog, Nabi 7, Xoom Family Edition, Nook or PlayBase.
Some of the positively-reviewed tablets at the moment include: Leapfrog LeapPad Ultra, Nabi 2, VTech InnoTab 2, Leapfrog LeapPad 2 and the Barnes & Noble Nook HD.
That would depend on the child, I think.

In ancient times children of wealthy Greeks and noblemen were taught in schools. Their primary tools of learning were scrolls and wax tablets which they wrote by scraping letters in with a stylus.
There are many apps available that can help children to step up their learning game when they are away from the classroom. Elearning apps are available for both iPads and Android tablets.
