Glowing rectangles

People spend lots of time staring at their screens (glowing rectangles).  Kids spend hours each day using their cell phones, computers, tablets, television and more.  Use that interest to motivate your student's analysis of screen ratios and what proportions they are looking at.GlowingRectangles

Not all screens have the same proportions.  Some televisions are tube televisions and they look more like squares compared to HDTVs.  Did you ever notice that movies and movie theaters use screen dimensions called wide screen?  Where do the iPad, iPhone, and other smart phone and tablet screen dimensions fall?

Use this investigation to discover and work with the proportions of all of these glowing rectangles.  Students will use ratio tables and grapple with open ended questions as they develop mathematical ideas about ratio and proportionality.  

Free Pizza for a Whole Stadium?

"Death Valley" stadium at Clemson University

Act One: Clemson Football Head Coach, Dabo Swinny, offered an amazing "poll party" with pizza for everyone if Clemson makes the College Football Playoffs in the last poll of the season.  See the written news story here.  See the news video clip of the press conference below. You might have to establish the context and vocabulary a little for some students.  "Death Valley" in this case refers to the stadium where Clemson plays home football games.  The polls are similar to polls in politics, like votes.  In this case the votes are from a panel of coaches voting for the top four teams in college football.

Graphic from:

When you look at the visual what do you see?  What does it make you think?  What do you wonder?

In this activity 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.  FYI: NFL teams play 8 home and 8 away games each season (not including any playoff games).

What’s your favorite sport?

SportsWhat is your favorite sport?  Wait, do I mean your favorite sport to play or your favorite sport to watch? Does it matter? Are your favorite to-watch sport and your favorite to-play sport the same sport or different? How does your list of favorite sports to play associate or correlate with your favorite sports to watch?

In this activity students rank a list of sports in order from favorite to play to least favorite to play.  Then they rank the same list of sports from favorite to watch to least favorite to watch.  Students take the rank for each sport and plot the points on the grid.  One example is pictured below.
