are jigsaw puzzles.
The kids love them. We have a half dozen or so, but they are tattered and incomplete relics of the 1970s. I've learned that puzzles pacify playground combatants, inspire teamwork, and make a noisy crowd quiet. They have saved me often when, at the end of the day, I am a mute heap collapsed in the corner of the classroom.
