Financial App (Pt 3 in series) – Let’s Talk About Money

pexels-photo-164501With the holiday season upon us, and people often spending beyond their means, it seems appropriate to continue the CG50 (and all Casio Graphing calculators) app exploration with the Financial App.

One thing we do not spend enough time on in K-12 education is financial literacy. I know there are some states that are trying to address this, but it is not enough. This lack of understanding about money, savings, taxes, interest, debt, etc. is a huge contributor to our enormous debt crisis. Take our current political focus on the ‘tax reform’ bill that’s up for a vote soon – most people do not understand the ramifications of this because they don’t really understand anything about finances and how taxes work. We do not in this country teach the basics of financial literacy, which is why we have so many people drowning in debt, losing their homes, barely surviving month-to-month on what they make, and forget about having the ability to save for the future. How many students really understand about saving money? Or how taxes impact their hourly wages (i.e. $10/hour is not that great when you factor in all the taxes taken out)? Or how not paying of your credit card monthly can make that $300 dollar purchase become a $400 or $500 dollar purchase?

When I taught in Virginia, they started a Personal Finance course ‘elective’ (only for stock-photo-working-coffee-phone-work-check-budget-finances-personal-finance-e841754e-765d-426e-af94-4b6a4ce9891fthose students technically not on the college prep track – which was silly, as ALL students should take a course on Personal Finance). I was lucky enough to be the pilot teacher in my school, so I could pretty much create the course. My goal was to help students understand the importance of financial planning so they could survive and thrive in the world, no matter where their path took them. We started with learning about different career options they were thinking of, and what a typical annual salary might be (so plumber, electrician, hair dresser, doctor, lawyer, teacher, etc). They learned to fill out job applications, and write resumes, and then we ‘pretended’ they had been hired and were receiving biweekly payments (I actually gave them ‘checks’). We learned about payments, investing, taxes, rent, credit cards, insurance, amortization,balancing a check book (the class had a ‘bank’), etc. They had to determine where they would live, whether they would get a car, how much they could spend on food, entertainment, etc. based on their salary. What they quickly learned is that their wages, after taxes, were often NOT enough to do much else – no fancy apartment and having to make tough choices (i.e. gas or food, no car, no expensive smartphone, taking bus, walking, no movies every week, no fast food, etc.) When a student comes to you all excited about their $9/hr job and all the things they will buy, and then realize after their first paycheck that it’s going to take months to have enough, it’s eye opening. And scary.

pexels-photo-164527What I learned is that we do not talk to students about real-world, practical mathematics enough –  simple things like saving money, calculating tips, balancing a checkbook, interest, credit card debt, etc. This is math they need in their everyday life. This is math that has purpose. This is math that will help them make smarter decisions about their future. Maybe if we did, we wouldn’t have so many people struggling to survive or believing every unrealistic promise they hear in the news..

My message – let’s get some Financial Literacy into K-12 mathematics programs!

With that said, here is a quick video on the Financial App that is available on the Casio graphing calculators. This video uses the CG50.

Summer Vacation – Use Your Experiences to Create Engaging Lesson Ideas

Sea Turtle at the Big Island, HI. How long do they live? How far do they travel??

I know most students and teachers this time of year are very familiar with Alice Cooper’s song “School’s Out for Summer”  (Seniors are probably focused on the line “school’s out forever….”  Maybe even some teachers!)  No doubt, summer is a time of rejuvenation for students and teachers – a much needed break, both mentally and physically. Note: Those of you who do not teach, and see teachers as having it ‘easy’ with the summers off, might try to spend some time in a teachers shoes before making those ridiculous assumptions, or read up a bit on what teachers actually do (they work more than 40 hours per week) and why summer breaks are so important.

Summer break is fast approaching for many, and some may have even started theirs. I remember those first couple of weeks literally not wanting to even look at anything related to school, students, or teaching. But – as most teachers will attest to, there comes a point where summer vacation weaves into professional learning or preparing for the next school year to begin. We never really turn off completely – we take classes to learn something new, or research some new technology or applications we want to try in class next year, or we revamp some lessons from the previous year. Summer vacation always ends up, at some time or other, connected back to teaching and learning – either personally for our own professional growth, or related to how we can be even better the next school year for our new group of students.

For me personally, everything I do always has me thinking of ways to create an interesting lesson for my students. It’s that pervasive idea that whenever possible, connecting the real world back to what students are learning will make the learning engaging and relevant. Just last week, sitting on the beach in Sea Isle City, NJ, watching this big machine out in the water that was dredging sand to replenish Avalon Beach, all I could think about were questions I would want my students to investigate.  Just a few of my questions, as I sat there:

  • How much sand is being pulled up? Is it from the same spot (my observation, since the dredge is in a different location each day, is that no it is not)
  • What happens to the sea animals and plant life that are ‘dredged’ up with the sand? Or, is there a filter that only allows sand in?
  • What are the impacts on the sea life?
  • How many hours a day do the dredges run? (seems like 24 hours to me!)
  • How long does beach replenishment last? (if you don’t have any storms to wash it all back to sea) How long does it take to replenish a beach?
  • How many pounds of sand is needed and where do they place the sand?

Lots of questions just from sitting and watching. What a great #STEM lesson this would be for students – there’s math, there’s science, there’s engineering and there’s definitely technology – it’s quite the endeavor. There is probably a ton of data out there and information about sand restoration projects, so you could have students researching, doing the math, checking out the science, investigating the machines used and the manpower needed. I did an initial search and found a couple articles already where I learned things like the grain size of the sand determines where the dredge pulls sand from (has to match the beach they are replenishing).  Pipelines are created to carry the sand from the dredge to the beach (so, how big are those pipelines? What happens after they ‘finish’ – do the pipes get removed?) Sometimes this is done to protect sea life, often times to protect commercial and residential properties, so this then begs the questions such as what’s the cost (money wise and to the environment), who benefits, what are the potential dangers and damage (to environment/sea life, etc). Here’s just a few articles I found.

My point here is not to give you a lesson on beach restoration. Instead, my point is that I was just sitting on the beach, enjoying my vacation, and saw the

machinery and started thinking. Posing questions. Realizing that there could be an amazing #STEM lesson here, which got me excited and doing research and yes – vacation or not – planning for teaching.  I think it is a natural tendency as a teacher to see a ‘lesson’ pretty much anywhere we go, which is what I want to emphasize here. Even on vacation, if you have a great idea based on something you are doing or seeing, some idea you think would be an engaging lesson, go with it. Take some pictures. Write down some ideas. Do some research. Use your own experiences and ‘time off’ to discover teaching ideas and spark your own enthusiasm for the next school year. Bring your vacation into your classroom and build relevant, real-world, multi-content lesson ideas that will spark student engagement, questioning, critical thinking and problem-solving.

Enjoy yourself and your summer, but never stop learning and looking for great ideas to bring back to your classroom.
