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...

The Scoop Last month, Edsource and The National Council for Teachers in Mathematics (NCTM) published an article making the case that high school math instruction needs an overhaul. 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:)...

Investment Math: Averages Can Deceive

What if you were told to choose from two investments: Investment A had an average annual return of 5.00% over a 10 year period. Investment B had an average annual return of 4.97% over a 10 year period.  Seems pretty straight forward, so I'm guessing that a majority of you would select Investment A since it has a higher average return. A few of you would be thinking, "this must be a trick question" and would select B. What if I then told you that the value of Investment B was almost 50%...

A good math exercise (or spreadsheet activity) that also teaches students about a popular stock market index and the power of compounding. It starts with a simple question: Do you think the Dow Jones Industrial Average will hit a 1,000,000 in one hundred years? From MarketWatch: Doubling, even tripling on that belief that U.S. stocks are the best long-term bet around, he tossed in a fairly bullish call. Buffett said he expects the Dow Jones Industrial Average to be ”over 1 million”...

From WSJ (Subscription required): Questions for students: Create a one sentence description for the trends seen in each of the two graphs. A friend says, “What a bummer that college costs keep rising at an incredible rate!” Using the data from the graph on the left, provide a response to her assertion. Since 1990, all consumer prices (aka the rate of inflation) have basically doubled. Using the rule of 72, make an estimate as to what the inflation rate has averaged from 1990-2016....

Hat tip to The Reformed Broker for this thought-provoking chart which will get your students thinking about the importance of asset allocations: Questions for students: Note: Equities are synonymous with stocks, fixed income means bonds, think of cash as a savings/checking account and alternatives would be alternative investments like hedge funds or private equity. What are the top four assets that millennials are investing in? Now rank the assets from highest to lowest historical return....

Another great interactive from Flowing Data allows users to see top jobs and salaries by state (and for the entire U.S. of A. also). This static chart that I copied from the site displays job and salary information for the U.S. The green areas in the chart are jobs where the Median Annual Salary is $60,000 or more. What’s cool is that you can set the Median Annual Salary slider (see above) to a certain Median Salary level and you will see what job categories have most of those jobs....
