with UNDERSTANDING

{ONE LESSON AT A TIME}

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. |

What’s included in the project?- Note to Teacher
- Project Overview
- Introduction to Cryptocurrency Activity
- Pick your Cryptocurrency
- Student Presentation Template
- Answer Keys
- Rubric
- BONUS: Exponential Regression Calculator Sheet
EVERYTHING included in this project is 100% editable! So, you can adjust to fit your curriculum needs. |

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!

Using data to find a quadratic graph of best fit is an awesome way to connect math with the real world. However, it’s not always easy to find authentic data to use for a quadratic regression equation. I REALLY wanted to use the flight of a soccer ball or golf ball and find a video on YouTube that had all the stats using a trace finder that states the distance and height. I searched and searched, but could not find a video that was clear and had the information needed to collect data for a scatter plot. So, I began looking at weather patterns, but that wasn’t quite right either. However, it helped me stumble across the timeanddate.com site. This is when I realized I can use the time of day and the altitude of the sun for a quadratic regression real world project! Of course, you can only use it for ONE day otherwise, it’s a periodic function. Here are the details of the project...

In this project, students are to find the curve of best fit for a quadratic function in the real world by performing the following:

- Choose a city, country and date for your research.
- Collect data on the
**relationship between time of day and the altitude of the sun.** - Record your information in a table.
- Find the curve of best-fit model using the quadratic regression feature on a graphing calculator.
- Graph the scatter plot of the data set and the curve of best fit in Desmos.
- Analyze the results.
- Record all of the information in a Google Slide Presentation.

VISUALS

The 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.

The project directions and rubric are 100% editable! This is very easy to integrate into any Algebra course either in-person or online, gives students some freedom of what place to research, and is mathtastically fun! And since it’s editable, you can even change it to record data over several days and find the sinusoidal regression equation for a higher-level math course.

Absolute value inequalities was not a topic my Algebra 2 students remembered from Algebra 1 AT ALL! I know that they hadn’t seen it in two years, but still, I felt like it was a completely brand new topic for them. This got me thinking that I need to have an absolute value inequalities project in Algebra 1 to help solidify this concept long term. So, I did some research on the Internet to find some ideas on a fun way to tackle this concept. I created the following project and my students had a lot of fun with it because it combines technology, shopping (who doesn’t love to shop?!), and of course math. Below is an overview of this project…

Every project needs to have a focus and goal. In this project, students are to…

- Define absolute deviation
- Research a type of product and record the various prices
- Find the mean of the prices
- Create and solve an absolute value inequality based on the mean price and the absolute deviation
- Graph the results on a number line
- Analyze the results
- Record all of the above information in a Google Slide Presentation

RESEARCHStudents choose a product line to research, such as different types of cars, phones, computers, clothes, etc. They also are to find the definition of math terms to help with their understanding. They record the prices and copy and paste pictures of each type. RESULTSStudents use the absolute deviation and mean price to create an absolute value inequality. Then, they solve and graph their solution on a number line. Finally, they determine which product(s) meet the requirements. VISUALSThe 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. |

As with any project, I do use a rubric, which is 100% editable for teachers. I also include a Google Sheet where you can type in each student’s product price and it will calculate the mean and deviation range, so you can easily check each project. I dread grading projects, as they can take a long time, but this rubric and spreadsheet make it so simple and fast!

This project is very easy to integrate into any Algebra course, gives students some freedom of what product to research, and is mathtastically fun! Here is a video that shows the example project I show my students before they begin:

I am always trying to create or find projects where each student’s project will be different than every other student’s in the class because it is more authentic this way. And of course, I want it to be applicable in the real world! This is not always easy to make because if every student’s project is different, or even has an unlimited number of solutions, checking each one is extremely difficult and time-consuming for the teacher. Well, guess what?!...the project I’m about to tell you about is authentic AND I was able figure out how each student could have a different solution. And at the same time, have an answer key for the teacher with all the possible solutions….I know, fabulous, right!! And it covers one of the most popular math topics…**Linear Systems of Equations**!

Oh wait, one more cool thing about it….it’s not quite STEM because there isn’t any engineering, but I’d say it’s**STAM (Science, Technology, Art, and Math)**…fun little twist…so check it out:

Every project needs to have a focus and goal. In this project, students are to…

- Research the growth of a tree and write an equation to represent the growth
- Determine when two trees will be the same height (algebraically & graphically)
- Analyze the results
- Create visuals to represent information about their tree and data results

Students select a tree from the Arbor Day site and find the growth rate range and mature size. Students write two equations – 1 to represent their tree’s growth over time and 2 - their teacher’s tree growth over time. Students use the substitution or elimination method to solve the system and explain the solution. Included is a spreadsheet where the teacher can record the student name, tree, and growth rate to ensure each student has a different growth rate.

Student’s us graph paper or Desmos to re-create their system of linear equations by graphing both lines. Students also draw, paint, or find a picture of their tree online and label it by finding specific characteristics of their tree. I learn a lot of neat things about different trees from each project. And students love the artsy aspect!

Students find at what year the trees are the same height and determine if it’s realistic based on the year each tree will reach their mature size. This helps students understand that not every solution in the real world will make sense, so it’s important to critically think about the results.

As with any project, I do use a rubric, which is 100% editable for teachers. This project is evaluated on the following criteria: neatness/organization, accurate research, writing a systems of equations and finding the correct solution, the graph, analyzing the results, and the visuals. I also include an answer key for the questions and all of the possible scenarios/solutions depending on the growth rate of each tree in comparison with the growth rate of the teacher’s tree. This is a HUGE time saver for teachers!

If you were to visit my classroom, you would see a lot of different ways students learn: guided notes, games, stations, activities, projects and more! Project Based Learning (PBL) is a great way for students to critically think, problem solve, and, in general, see math differently. Therefore, I try to integrate a project into every unit and make them as “real” as possible.

One of my favorites, and my students, is the Parabola Selfie Project. In this project, students take math outside of the classroom and explore the real world to find a parabola.

Let’s take a quick look at how this project is broken down…

One of my favorites, and my students, is the Parabola Selfie Project. In this project, students take math outside of the classroom and explore the real world to find a parabola.

Let’s take a quick look at how this project is broken down…

Students find a parabola in the real world and then take a selfie with it. Why take a selfie, you say? Well, first of all, it makes it fun for them since selfies are something they do often and share on Facebook, Snapchat, Instagram, or some other form of social media. Second, I want to make sure they don’t just Google search a picture online. That would take all of the fun out of this project. There is so much in the world to investigate, so I want them to go out there and see math as much as possible.

Next we pop that picture right into Desmos, which is an online graphing calculator. Students adjust the scale of the graph to match the dimensions of the real life parabola. I’ve even created a video showing students how to do this, in case they are not familiar with Desmos. Then they write an equation for their parabola and analyze the parabola by finding characteristics such as the axis of symmetry, vertex, domain, range, etc.

In almost every project I try to create a fun little twist that involves students observing or reviewing each other’s project. In this one, I have students exchange their graphs with each other and use the Parabola Swap table to record their information. This will give students an opportunity to identify characteristics of another parabola and also receive feedback on the accuracy of their data.

I rarely have students complete a project and then individually present to the class. It takes up too much class time and sometimes it can be difficult to see and understand the data when in a slideshow. I’d rather students take their information and put it on a poster or in a report format. Then we do some kind of walk around to view all the projects up close.

For this project, since students already swapped parabola graphs with another group and filled out the characteristics table for that graph, I don’t have them fill out another form when they do the walk around. Instead, I have them view each project and then vote on who found the most unique parabola in the real world. I give out a prize to the first and second place winners. You could give out a homework pass, food, or anything that your students enjoy. This gives each student a little more incentive to really find a fun and unique parabola.
