They are 9, 13 and 15. They say the are bored but also say they don't understand when they watch the dvd or when i tell them. It seems to take a while to grasp what they are tring to learn. Not so bad for my 9 year old but more for the older ones. I have a % yr old and a 3yr also. So I want to try to find some thing that make learning fun. Chevcking out tyhe web page, Thanks.
