Was Belicheck's math right when he said: "I thought it was our best chance to win."

Was Bellichick's math right when he said "it was our best chance to win." I agree with him. Kick or pass: Which was a higher probability? Anyone want to offer an analysis?

Here's mine.

Probability of Patriots getting a first down on 4th and 2? I say 90%. It's only a guess but given the Patriots football prowess along with the element of surprise, I say they would have made it on average 9 out of every 10 times they tried it. On the other hand, punting to the Manning machine is a shaky 50-50 proposition at best. Also, what are the chances the receiver would bobble the ball? Video of play.

What do you think?

WCYDWT (What can you do with this): How Big is the Gorilla?

Here's a good slide to show to start a conversation about decimals with your class. The first question that comes to my mind is: So, really, how big is this gorilla? What are some of the questions that come to your mind?

Most textbookish review sections for decimals are pretty boring. How might this help? Putting a common idea in a interesting, surprising way will get the kids attention. Now how do achieve your math objective with that?

What would you do with this sign?

I've tried it with many 6th grade classes. Have gotten some interesting results.

Measuring Circles: Good idea, bad pedagogy?

From the WCYDWT files:
Watch this video and tell me: Would you show this to kids as is? Anything missing here? If so, is the missing thing necessary?

What's Wrong with this Picture?


Hint: It appeared as an ad in the program book for the NCTM conference where the theme was EQUITY. Hello? Anybody home?
