 Cryptocurrency began in 2009 and has been a phenomenon ever since! The value of several cryptocurrencies has exponentially increased over the years. This is REAL WORLD math at it’s finest! Okay, admittedly, I knew next to nothing about cryptocurrency, besides that it existed, until this year. More and more of my friends and family have been interested in and investing in crypto. It got me very curious about what it is and why are people buying it. As I dove more into it, I realized that the trend of several cryptocurrencies would be perfect for an exponential regression project. And quite frankly, digital currency is VERY exciting, as this isn’t something we’ve experienced ever before in history. It’s a brand new type of currency! So, here are the details… In this project, students will take a closer look at the price change of cryptocurrency and where it is potentially headed in the future via historical data and finding an exponential equation of best fit. What is cryptocurrency? I’m sure you’re thinking that if you don’t know anything (or much) about cryptocurrencies that you can’t use this project with your students. WRONG. I’ve included a “Cryptocurrency: What is it?” introduction activity. This will help give the students (and you) enough basics about cryptocurrency in order to complete the project.  CRYPTOCURRENCY: BITCOIN AND BEYONDOBJECTIVE Students are to find the curve of best fit for a exponential function in the real world by performing the following:
RESEARCH & COLLECTING DATA Students are given a specific cryptocurrency to research. The research includes finding the ticker symbol, learning what their currency is, three facts about their cryptocurrency, and collecting pricing data for their currency over a specific time period. GRAPHING & RESULTS Students use the TI-84 graphing calculator to find the exponential regression equation. Then they use Desmos to create a scatter plot and graph the exponential regression equation. Students answer questions to help them understand and analyze their results, including future price predictions for their cryptocurrency. VISUALS A Google Slides template is provided, so students can type in their information in the specific location. They then can easily turn their project into you via Google Classroom or email.  GRADING An answer key that gives the data, equation of best fit, and the answers to the questions is included for each cryptocurrency. A rubric is provided, so you can easily evaluate each aspect of the project. It is great for students to use, so they know exactly what is expected of them.
Most of my students knew nothing about cryptocurrency when they began this project. But, they were intrigued because they’ve heard about cryptocurrency AND knew some businesses that were beginning to accept it for payment. Why not learn more for themselves?! This is a cutting edge project that you don’t want your students to miss out on! Click on the cover below to go directly to this project:  More mathtastic real world projects for your students:
