We have a couple of them at home - ¿Adivina Quién? and Cadoo. I bought both at our local Walmart in the clearance aisle. They're also available at Amazon.
The object of the first game is to guess the mystery person on your opponent's card by asking one question per turn. You have to have a keen eye and really notice the differences among the faces on your board such as hair and eye color; some faces have beards or mustaches; some are wearing hats or glasses.
Now, your wheels are probably turning... wouldn't this be a great game for learning parts of the face in Spanish? YES! Adam, age 8, likes this game. I have given him a little cheat sheet with the hair colors and such, but I have noticed that he's not referring to it as often now. I think this would be a great game to have in centers in your classroom - perhaps third grade and up.
Another game we have is Cranium's Cadoo in Spanish. The object of this game is to get a Cadoo which is four play-pieces in a row (up, down, horizontal or diagonal). To get to this point is really a lot of fun. You either are sculpting something with the clay, acting, drawing, or solving a puzzle. I have to help Adam with this one, but he still enjoys it. I'd probably recommend this one for perhaps middle school and up - depending on the level of Spanish of your students.
I have modified the game a bit so that I can use it with an elementary age student I tutor. I made up some different cards to go with the vocabulary we're learning. For instance our subject was going to a restaurant. Some of the cards were:
Interpreta lo siguiente: el mesero
Modela esto con plastilina: la mesa
Elige la cosa que no pertenezca: a) la cuchara b) el tenedor c) el gato
There are quite a number of board games in Spanish available now. It's a great way to learn and have fun at the same time.
