My 11 year old daughter loves the educational games on Squigleysplayhouse.com. The exact links to the educational games is http://www.squiglysplayhouse.com/Games/LearningWord.html
Education in the sense we have to learn the lessons like maths, science whatever we choose and there will be the teachers go guide. If i come to the part of maths in maths everything we cannot access by learning from others so if we have to do by our own so if we use this types of tricks as subtraction, sudoku these games make us to learn by ourselves.
