I had the bright idea to unplug my Wii and take it to school! I think it was the most engaged my class of 35 students had been all year! Since then, I make a point to have "Wii day" a couple of times a year and the kids could not be more excited!
I have looked on Amazon and found a couple of other educational Wii games, but haven't bought any yet. Maybe future grant?
ThinkSMART appears to have games best for high school: Science Papa lets you explore chemistry, biology, physics, and paleontology through science experiments.
Reader Rabbit has a couple of games for early elementary grades (I think I saw Pre-K through 3rd grade).
My Word Coach looks like it would be great for GT and high school classes, but may be a fun warm-up for a typical middle school classes too.
Jump Start advertises being great for ages 5-9.As if you haven't seen this show! Upper elementary classes would love this:
We recently bought an XBox Kinect for our son and may have to start checking out games for that too! If you know any other games, please share!
