Playtime isn't wasted time: it's intensely educational

Yesterday I came across an article by Lenore Skenazy:

[Peter] Gray is a professor of psychology at Boston College and a co-founder, along with me, of Let Grow, a nonprofit promoting childhood independence. He writes often about how kids need to play; this is how they learn how to get along, be creative, make things happen and grow up. Playtime isn't wasted time; it's intensely educational, just not in a standardized test kind of way. When administrators replace play with academics, the gains are short-lived, but the damage is not.

But as her article says:

Increased academic pressure and testing in kindergarten is bringing everyone to tears - including the teachers.

All of which gives me an excuse for posting the video above, which I was promoting in the day job on Friday.
