Game with class - Designing and using games in education by tenuki
"I wanted to take some time on here to point out a few of the companies that I would heartily endorse and recommend educators interested in games check out. The first company is Looney Labs. Looney Labs is probably most famous for the card game Fluxx (which is available in several languages - I have used and written lesson plans for Fluxx en español) as well as for their pyramids."
