Consumer Math curriculum: coming summer 2022

Teaching consumer math is a passion of mine. It breaks my heart when young people are taken advantage of financially, whether it's from accepting a high interest rate on a car loan or misunderstanding a credit card's minimum payment. It's important for students to understand personal finance at a young age.

The person on the left with a 787 credit score will pay $492 per month for a new car and is also given the option to lease. The person on the right with a 507 credit score is given no option to lease and will pay $619 per month for the same new car.

Here's a recent image compiled from a nearby Honda dealership's "build my deal" feature. I typed in a $5000 down payment for each but a 787 credit score in the image on the left and a 507 credit score in the image on the right. This represents two people needing new cars.

The person on the left with the 787 credit score has a smaller monthly payment with the option to lease. The person with the 507 credit score has a higher monthly payment with no option to lease. How did the person on the right end up with a low credit score?

What does a credit score mean and where does it come from? What are some ways to improve this score? What is the difference between a debit and credit card? How do I get my tax return? How much of my paycheck will be taken out in taxes? Was I paid for the hours I worked last week? Can I afford a car?

I got A TON of questions just like these while teaching high school consumer math. Many of the questions were about things I assumed my students would already know. But how would they know? My students were seniors and worried about life after high school. Understandable! Because the textbook we had for the class didn't answer their questions, I ended up building the course myself from resources found all over the internet. 

Coming soon: Consumer Math Curriculum

Becoming more financial literate is empowering. Empowering young people to understand their finances is extremely important to me. After years of milling over the best way to build a printable curriculum, I am SO EXCITED to say that I am currently working on a consumer math curriculum. It will be available for download from my new site in Summer 2022.

The curriculum I am building is the curriculum that I needed while teaching consumer math. It will consist of a printable book, accompanying student note pages, editable quizzes and answer keys. Topics covered in depth will include:

 

Wants vs. needs ✓

Checks and registers ✓

Wages and salary ✓

Bank accounts ✓

Budgets ✓

ATM, debit and credit cards ✓

Credit score ✓

Discounts and coupons ✓

Tax and tips ✓

Percent change ✓

Unit pricing - ✓

Income taxes - ✓

Car loans, mortgages, student loans - currently building

Retirement planning and Investing

Answer keys 

 

This consumer math curriculum will be a comprehensive and approachable guide for high school seniors. As I work though building the curriculum, the above list may grow. To keep me moving to meet my summer 2022 goal, I will add a ✓ next to each completed topic. 


I'm so excited for this project. It's been a vision for so long that it's so exciting to finally put it all down on paper.

If you teach high school consumer math, financial literacy or personal finance, I just started a new Facebook group that I'd love for you to join: High School Consumer Math Facebook Group

Hands-on geometric transformations in the coordinate plane

In this post I share an easy, hands-on method for demonstrating reflections and rotations of geometric shapes and their coordinates in the coordinate plane. The video included in the post covers reflecting over the x-axis, over the y-axis and over the line y = x. This same method will work for reflecting over any line of symmetry in the coordinate plane, even linear equations. I then share an idea for showing geometric rotations with a hole punch.

Last week, I wrote a post about using a hole punch to find function inverses in the coordinate plane. A few people asked on Facebook if the process would also work for geometric reflections, and it absolutely does!

Numberless Quadratics Activity

"But Miss, these word problems don't have any numbers!"   "You're right! They're numberless word problems!"    This was the conversation with my algebra 2 students at the start of our quadratic word problems unit every year. I LOVE teaching quadratic word problems, especially because students always start super intimidated and end the unit super confident in themselves for having accomplished something big!   But the language! How long, how high, hits the ground, time in the air... these simple sounding phrases can be pretty confusing at first. To focus on what these phrases meant and what they were asking us to find, I liked to start our projectile motion unit with a numberless quadratics activity. Presenting students with word problems with no numbers forced students to look for the quadratic keywords as clues to what they were being asked to find.

How to find inverse functions with a hole punch

Are your algebra or algebra 2 students learning how to find inverse functions? Here's how to make the process of finding function inverses easy, visual and hands-on-- with a hole punch!

This same process can also be used for reflecting any graph or geometric shape over the x-axis, y-axis, y = x or any other line of symmetry on the coordinate plane.

What the heck are fraction exponents?

Fractional exponents are a little weird. They force us to think backwards, to ask, "What number multiplied by itself yields the base?" If this questions sounds familiar, it's because we ask the same question when figuring out square roots (and other roots). In this post are 3 visual examples of rational exponents, how we can think about them and how we can evaluate them.

Rational exponents are just another, calculator-friendly way of expressing roots.

Exponents using Visual Models (video)

Why is a number raised to the zero power equal to 1? And why do terms with negative exponents become fractions? Are we able to see this through visual models?  Yes!   In this short video, you'll see how exponents take on a pattern and can be modeled concretely with cut paper. We'll start with 3 raised to the 2nd power and work our way to 3 to the -2.
