Hawken Math

This is pretty bad ... and most would never have noticed.

Some of the comments are crass, but the problem is funny. I'm on the fence as to whether this is clever or a "trick" question...

I didn't see you posted this until I posted one. Great article to share with students

This is a great article! And I had to chuckle at the reference to shark week since my husband has been watching it. What a great project idea....how can we solve this problem?

A brief preview of some of these sites, but there might be some that are potentially good.

This problem isn't remotely unique to Khan, but I'm a bit put off by the "Learn the Skill" call. That said, here are my potential additions: 1) What are the lengths of the hypotenuses? (easy) 2) How many triangles until the hypotenuse length exceeds 5 units? 3) How many triangles until the SUM of hypotenuse lengths exceeds 5 units? (never done this. How would a MS or geometry student attempt?) 4) How many triangles until the figure begins to overlap itself? (never done. How would a MS student attempt?) There must be many other GREAT problems here. Thoughts?

Once a student understands exponents, this is a brilliant problem to inspire student thinking.... Even if you just do the 2-digit version...

An interesting approach to k-12 math program. I liked the metametanome.

Very funny, Becky. I taught with John, the post's author, in ATL. Good guy. Not easily impressed. All the more power to his St. Ann's visit. FYI, those folks are also the authors of the Math Munch site we used so much for last year's math club.

The Venus-Earth orbit is surprisingly beautiful. The others are gorgeous speculation.
