good sites for children to use

[naflharrison]

does anyone know any good online learning sites that i can use with my daughter. she is 5 and although very smart she sometimes lacks concentration and im tryint to find fun ways to make her remember things easily. she tries to do sums in her head instead of using her fingers which sometimes means she makes mistakes. dont get me wrong im glad she makes the odd mistake as it shows she is doing it herself and trying but its getting the concentration with fun learning so any good sites would be really appreciated. tia
