Because of climate change, we've been having too many extreme weather events. There have been unusual droughts and heat in the West, an increased number of hurricanes, severe flooding, and high winds throughout the midwest.
Use the open number line and our lists of temperature extremes to make signed number operations and absolute value sensible. Students compare record high and low temps (integers) and use absolute value in order to always find the positive difference. Subtraction of negatives becomes obvious in this lesson.
Basketball is back, being played in the "bubble" in Orlando Florida. Teams are competing in the playoffs and the NBA Finals are right around the corner. Let's do a little sports history and data analysis through the context of NBA Finals math! In this activity students consider scatter plots, circle graphs, bar graphs, Venn Diagrams and the concept of mean.
To start the activity check out the Infographic below. What do you notice? What does it make you think? What questions do you have? How does the average age of NBA champion teams compare to the league's average team age? How can we use this information to help us predict future NBA champs?
Infographic created by Paul Van Slembrouck, @ptvan at paulvanslembrouck.com Original data compiled by Idris Raja.
Continue exploring NBA championship data in our handout by exploring the dominance of a select few teams in NBA history. Students work the data, data representations and statistics. For which kind of observations are circle graphs or bar graphs most useful? Who has won the most NBA titles NBA history? Lots of math!
What is this holiday about? Are we celebrating the start of school? New cars? The end of summer?
In this short activity, students learn about the intended meaning of Labor Day as they read about its origin. For the mathematical part, they look for patterns in the history of Labor Day dates. Students then use those observed patterns to predict future dates of the holiday.
The U.S. Postal Service has been in the news lately. Does it seem like your mail takes longer to reach where you have sent it now? Do you wonder why there are delays and whether things will change soon? Read about the issues and make your own conclusions.
In this activity students appreciate the incredible network of workers and machines that sort and deliver about 150 billion pieces of mail each year. Students learn how it is all funded and try to decide how the Postal Service could earn more or spend less in their budget. They finally get to think about whether the post office should be a government run service or a self-sustaining business.
