Interesting chart showing the linkages among users of social media platforms (from Pew Research); great data table to build analytical and critical thinking skills using a topic that engages your students: Note: Reciprocity between websites refers to the percentage of users of one site using another website. In the chart above, 27% of Facebook users also use WhatsApp (which curiously is owned by Facebook).  Questions: Which two social media sites have the strongest linkage (or...

I thought this would be an interesting question and interactive to get your personal finance class off to a great start this year. It takes a step back from talking about money and forces students to think about what they value most when it comes to life. It will also allow them to 1) see what countries match up best with their definition of a better life 2) see how their answers compare with others in the U.S. and 3) have them think about the relative strengths and weaknesses of the U.S....

Hat tip to the Wealth of Common Sense blog for updating their performance charts which help demonstrate a key concept in investing: risk. Risk is one of those nebulous concepts for teens who have never experienced a severe market correction while holding stocks. These charts help elucidate risk from a mathematical perspective by plotting returns for the three basic asset classes: cash, bonds and stocks. By using the same scale for each, it becomes more apparent which is the riskiest asset. ...

Maggie Roble’s students at Centennial High School in Corona, California asked relentlessly why there was no class on practical, financial math they could use outside of classroom. She decided to change things for the better and built a math class from the ground up that would provide her students with those "real-life" skills. She clearly built something the students love? Since the program’s inception just two years ago, she has increased the number of students in her program from...

In the piece, the NCTM calls for math course offerings that allow students to be “prepared to use math to understand the world around them and [have] an appreciation for the important role math plays in society.” NCTM President Matt Larson goes on, “we hope students will come to understand the beauty...

So yesterday was the beloved TAX DAY here in the US. Funnily enough, the IRS website was down so maybe those procrastinators will get lucky and be given an extension (update: they were given one more day). I’m sure that students are asking all types of tax questions due to both current events and the tax season, so it is only fitting that we highlight a Taxes Activity related to Math for our Math Spotlight this week! Drum roll…To kick it off, CALCULATE: Completing a 1040EZ is a...

Incorporating Math into a Personal Finance Classroom & Financial Concepts into the Math Classroom. When we started this project, I thought deeply about my years teaching physics. For instance, I wanted to take a related and important topic, like Climate Change and insert it into my curriculum, but I ran into a number of challenges. The physics concepts associated with Climate Change were too advanced for my students and the climate change concepts were often too surface level to relate to...

Brian Bean definitely took the road less traveled—though not always of his own accord—to become a teacher. After a Ponzi scheme he invested in went bust, he vowed to teach the younger generation about money management. What his students simulate in his classroom economy at Tomball Memorial High School (TX) will undoubtedly be situations they face in the “real world,” and Brian wants to prepare them as best he can. This personal finance math teacher extraordinaire has...

What happens when you show up on Friday night at your favorite diner with a group of friends and realize you are #10 on the waiting list? You could walk out and go elsewhere but nobody has better grilled cheese and chocolate cheesecake OR you could treat it as a math problem and try and come up with an estimate of how long the wait is going to be. You count all the tables in the diner (15 or so) and figure that most meals here take about 45 minutes to complete (they like to turn their tables:)...
