Your point at the end is so true. I was reading that list of examples and thinking "Why are they putting the emphasis on boys? Every single one of these looks like something I'd have enjoyed in school."

A good example of bored boy behavior vs. bored girl behavior: one time in a personal finance management class, we played BINGO with elbow macaroni as markers. (The questions were really simple so the game was neither fun nor educational.) Quite a few guys in the class took to stomping on their macaroni and finding other creative ways to crush it. I was busy getting them all to stand up as little arches and looking for interesting ways to arrange them. I was just as bored but less disruptive.
