# Super Bowl posts and Groundhog day, 2015

Clean close shave - Brian shows a graphic that correlates facial hair to quarterback ranking and allows you to bring up sampling, causation versus correlation, misleading data, measures of central tendency, variability and data visualization

Deflate-gate - Students work with a negative number line to define and express the present controversy of under inflated footballs.  Using a football gauge that reads zero when the football is properly inflated at 13 psi, students express the values by graphing, using expressions, and inequalities. A little physics lets them evaluate the validity of temperature change resulting in this loss of pressure.

How have the cost of Super Bowl ads changed? - Students analyze and graph our data of all of the previous Super Bowls and decide whether the change in ad cost is linear, exponential, or something else.  Then they predict the cost of the future ads.

Super Bowl Numerals XLIX - Roman numerals are rarely taught in our curriculum but they are used in our society.  Give students a chance to do some really cool addition with Roman numerals and refresh their meaning.

Typical Super Bowl scores - Encourage your students to guess what the final Super Bowl score will be.  Analyze the data in class finding the mean, median and range of past game scores.  Then give students the opportunity to correct their predictions.  Follow up after the game.

Groundhog Day - Sunday, February 2nd is also Groundhog day.  How often is Punxsutawney Phil correct in predicting the coming of Spring?  Relative probability can be introduced and mastered with our activity using Phil's past predictions.

4th down - Use data to analyze whether to "go for it", punt, or kick a field goal.

And how about some bonus NFL or Super Bowl related activities:

Watson Saves -Watch the video with your class and use our activity to motivate students to figure out who ran a greater distance by using the Pythagorean Theorem.  In the video Teddy Bruschi says that Watson must have ran about 120 yards, maybe even more.  Use the video and/or our activity to see if Teddy’s estimate is about right.

Losing Teams in the Playoffs A look at the worst teams (by regular season record) to ever make the playoffs in the NFL, NBA and MLB.  Fractions, Ratios, Percent.

NFL Home field advantage  Students use an infographic to compare NFL team home and away wins.  Students consider the best home team, the best away team and consider if NFL teams really do seem to have a home field advantage.

Which TV is the Best Deal? Time to buy a new HDTV for the big game.  Which TV gives the best deal considering screen size?  Integrates area and unit rate.
