Triangle - Monkey in the Middle
Three passers are assigned to each side of the triangle with one defender in the middle. The Outside Passers will pass the ball to each other, while the defender tries to block/ steal the ball from them. If the Defender gets the ball, the kids switch, so that there's a new defender. Also, don't let the passing go too long without them just changing defenders (as some kids may have a harder time blocking/ stealing the ball, than others).
