This activity uses the results of the 2016 Presidential Election, as well as all the previous US Elections, to determine if it was, as one ignoramus called it "a landslide." By examining previous election results based on their electoral college and "popular" vote, students will see for themselves using factual data that "landslides" in US Presidential Elections are fairly unique events, and then decide for themselves using the actual facts as compiled by the US Government whether the results of

This is a set of activities that uses the raw data from each state in the 2016 United States Presidential Election, including the number of votes for each candidate, the number of "eligible" voters and the number of voters who "did not vote." What students will find out that if "did not vote" was a candidate, it would have "won" by one of the largest landslides in history. This is based on data used on the following website: https://brilliantmaps.com/did-not-vote/ The first activity explains som

This is an activity that analyzes the legitimacy of the "electoral college" system of voting in the United States, and whether it really is based on "one person, one vote." It uses census data from 2010 to show that when it comes to influence on presidential elections, states with smaller populations have a disproportional effect on the outcomes. The activity begins by explaining the workings of the electoral college system, describing how each state gets one elector for each house member, plus

This is an activity that uses data collected by the Southern Poverty Law Center tracking the use of Confederate symbols in the form of monuments, courthouses, schools, and other public amenities, including parks, highways and holidays. The activity takes place in 3 parts: The first part is that students assemble and label a timeline that tracks the rise of Confederate symbols from 1860 to the present day (2016.) In the second part, students match dates to 10 different events in Civil Rights h

This is one in a continuing series of activities that takes mathematics and applies it to social issue, including Food Waste and Mathematics: From Farm to Table to Dump, Mathematics, Demographics & Slavery: The 1790 Census in Ratio, Percents & Graphs, MathBusters: Percentage Practice to Analyze 2016 Election Results, and Statistics, Histograms and Lies Presidential Candidates Tell. In this case, we are looking at how far food must travel in order to make it from where it is produced to the place

Here's a very uncomfortable fact: it takes 4 pounds of potatoes to make 1 pound of potato chips. That means that for every 1 pound bag of potato chips you eat, 3 pounds of potatoes have to be thrown away. What a waste of food! This is a series of activities that looks at the hidden world of food waste. It includes a look at how much food is wasted as it is "processed" into finished products like french fries and potato chips. It also includes mathematical activities where students calculate how

This is an old brain teaser that someone told me, and which I shortened and clarified, as well as added clues for your students to use, as well as three different explanations for how to solve it. Basically, the problem goes like this: you have 7 people who want to find the average of their salaries. The only problem is that no one wants to tell anyone how much they earn. How will you find the average without anybody stating their actual salary? I've run this problem by all my techie type frie

This is one of an occasional series of mondo-tough problems that use small numbers (or no numbers at all!) Here’s how it works: we all teach our students how to take a group of numbers and calculate the range, mean, median and mode. Seems pretty simple, and our students tired of it damned quickly. Can you blame them? It’s just “do what the teacher told me to do, and then write the answer here...” kind of busywork. But what if we were to switch the tables on our students: let’s give them t

Since the first modern Olympics in 1896, runners in the 100 meter sprint have been setting records on a regular basis, earning the title of the "fastest human on earth." How long can these records be broken? Will there eventually be a runner who can do the 100 meter sprint in just a few seconds? This activity shows students how the change from measuring time from tenths of a second to hundredths of a second allowed more records to be broken, and that by graphing these records, the new records ca
