Geez that Dan Meyer knows how to maximize his Klout score. This is a really great use of twitter. Here is his tweet:

Might as well stick with Dan Meyer some more with this really nice real world metric/imperial conversion task. Nice rework of this basic textbook question. Once again, Twitter to the rescue. It is interesting how minor tweaks can spice a question up to be more problem solving.

Why not end on some humor. Some real bad math here in a bunch of visual examples. For example, see if you can spot the error in the quadratic formula (its actually hard to see but its there):
