During the Fall 2011 the 7 billionth human on earth was born. The counter mentioned above gives updated approximations of the current world population. When will we hit 8 billion people? Students look at the number 7 billion, try to grasp its enormity with some comparisons, check out population, calculate some population density, work again with percents and have some fun thinking about our globe and where we live.
The Occupy Wall Street (OWS) movement has grown since it began on September 17th. Students can look at charts that show percent mentions of the demonstrations and calculate the percentage of media mentions, percentage of comment growth, and the percentages of American wealth. Again Twitter was the prime discussion vehicle.
Your students have probably seen these images around and might not know why they are becoming popular for smart phone scanning ... and possibly dangerous. Students figure out the number of permutations of symbols that are possible with these 2-d scanning codes and compare that capability to the capacity of ordinary UPC barcodes. This activity might open student's eyes to some of the marketing that surrounds them and help them become aware of some possible dangers … all while engaging in mathematics.
Millions of people and businesses use debit cards every day. Banks didn't charge customers for their use. Banks actually gave rewards and incentives to customers for using them.
So how did banks make money from debit cards? Banks charged the businesses that accepted those card payments. Merchant transaction fees averaged 44 cents per transaction, but, due to a new government regulation, fees are now capped at 24 cents.
It is estimated that the banking industry will lose billions. Some banks are now starting to charge their customers a monthly fee for card use. Bank of America just made the news by announcing a $5 per month debit card fee. Customers are angry.
In this activity we take a look at the math behind this fiasco. Will Bank of America come out ahead or lose money with the new debit card fee structure?
On Monday, the space shuttle Endeavor launched for the last time. The six astronauts on board docked this morning at the International Space Station to join the 6 astronauts and cosmonauts who live at the ISS.
Combine current events, Earth science, and parabolic motion in your math class. Students will use their understanding of exponents and practice converting speed and distance from metrics to US customary units to complete this exercise ... and, they will learn about space science in the process.
