Great new way of visualizing data (all kinds of data sources). Make wordles, graphs, webs of all kinds of information. Also a great place to get data sets for investigation in the classroom. 

Yet, another great data analysis, display tool from Google. Implications in helping students organize/display/analyze/evaluate data is incredible. Displaying data through a map has implications in so many content areas.

Movie box office data that is current and very comprehensive. Several different trends are easy to track including exponential, and log functions. Great for using with students to create regression models, making predictions based on the models, checking the results and re-analyzing. Also, when a movie doesn't follow the predictions there are often easy to understand reasons for why the movies behave differently (a holiday weekend may cause the movie to gross more on a given weekend than predicted, etc.)

"Visualize your numbers, explore charts, and share insights with others. " Great data source. Students can explore data sets, identify different ways of representing data, as well as identify different characterisitics of data.

Very interesting. Remember that to convert a:b odds (against, which is what the folks laying the bets will give) to probabiilty you take p=b/(a+b). This site lists the Yankees as 2:1 to win the American League, so if you think the probability is greater than 1/3 you should take the bet (theoretically speaking; please obey all applicable laws!). The Red Sox are 7:4, giving p=4/11.
