GreenWeaver-For online learning games, I love Quia for my kids. Quia often models games after successful television game shows in order to teach various educational concepts.
For example, when my daughter was having difficulty with subjects and predicates, I was able to go on the site and they had a game that was modeled after, “Who Wants to be a Millionaire.”
The questions all had dollar amounts and when the level of difficulty increased so did the dollar amount which made the game really entertaining and fun. I love this site and my daughter got a 100 on her test as a result.
