Operation is a fun game that helps kids to learn different parts of the body, by having to remove them from the outline of a body. It is hard to remove the body parts without touching the edges and being disqualified, so it teaches fine motor skills as well. Of course the kids don't care about this, they just dissolve into giggles every time they miss a piece. My daughter and niece both have tons of fun with this game! It is also great for an only child as they can play by themselves and don't need other players (though more than one can play!) I highly recommend this game!
