Tim Tebow is the talk of the sporting world. This Saturday he goes up against Tom Brady and the Patriots in the Playoffs. I keep hearing about "Tebow Time" and I wonder at what point in a game that usually occurs? Have your students take a look at Tim Tebow's situational stats, by quarter, and overtime to determine when Tebow is at his best. Ask students to support their claim with graphs or statistics.

## The Euro and the international debt crisis

Lately the news is filled with talk of the Euro, US foreign debt, the fragility of European monetary systems, and the interdependence of all of these crisis.

In this activity students become familiar with the Euro, practice translating the Euro's value to dollar amounts, and work with comparisons of debt, gross domestic products, and average debts per person. Students will gain a better appreciation of what the news is all about. They will become familiar with the value of the Euro, can appreciate the complexity of the present financial crisis, and will be able to contribute to financial observations and discussions at home.

In this activity students explore scale, similar figures, volume and measurement as they estimate the amount of coffee that this record-sized mug holds. Students also consider how many cups of coffee this mug could produce and the value of the coffee held in this mug.

## Launch of the next ISS crew

If all goes well, the next crew of the International Space Station (the ISS) will launch on Sunday, Novemeber 13, 2011 from the Baikonur Cosmodrome in Kazakhstan.

Keep your student informed and excited about what is happening above our planet by letting them calculate the roominess of the Soyuz transport as compared to our retired Shuttles. Students analyze the costs and capacities of the two vehicles (Shuttle and Soyuz) and come to some conclusions, as our space agency did, about the kind of vehicle that gives the most benefit for the buck.
