Real Life Math in October

It’s the first Wednesday of October which means it’s time for our new linky – Math IS Real Life. August and September were super successful!  We’ve even created a Pinterest Board of all the posts that were linked up at the end of August!  We will continue to pin them each month to keep all of these AMAZING posts in one location!
If you are linking up, please include the below picture AND a link back to all four of our blogs – feel free to use the 2nd image and the links listed below!

What could be more real life to me each week? Well of course it’s my once a week coffee house trip that I allow myself as a pleasure to enjoy getting out of the house/office. I have a few different places that I go and have been thinking about the various reward programs they each offer to see if I need to start hitting up one more than the other to make the most of the program.


So the drink above was from a recent trip to Starbucks and cost $5.79. It was delicious and I enjoyed every bit of it {especially since our air is our right now}. Since Starbucks is one of my three choices around here, I decided to look into their loyalty program and see if it would pay off for my once a week habit.

To become a member of My Starbucks Rewards you have to have 30 separate purchases on any of your linked cards during a 12 month time span to then achieve and remain Gold status for one calendar year. {source}

At that rate, I would spend $173.70 if I bought the same drink each time (I don’t, I occasionally change it up.) and would then have earned my free birthday treat. (so $5.79 earned for $173.70 spent- nevermind the fact that it would be roughly another 4 months until my birthday)

So roughly a 5% return on your investment of yummy drinks over the course of time has me to thinking that maybe the rewards program at Starbucks is really geared toward the consumer that is on a first name basis with their Barista {no offense, my former Barista Corey was the best Barista I had for 3 years and he even sang at my wedding}.

So, while you are just analyzing the facts you are truly looking at variables and equations to determine if the reward pays out in the end based on your consumption.

  1. Older students, especially those with a new or imminent driver’s license, will be both fascinated and educated by Calculating a Car Payment . Here, students visit a virtual used-car lot and select a car. Then they use formulas that include complex fractions and large exponents to calculate the monthly payments on their virtual dream car. This is a short lesson, but students may be inspired to use it as a springboard to other automobile-based activities. For example, Online Math Applications’ Trips page contains mini-lessons on the costs of leasing, owning, and driving cars. Students can examine such topics as the relationship between the number of stops and the number of possible routes, how to determine the shortest route, and the relationship between speed and braking distance. The site contains formulas and quizzes and provides opportunities for students to create their own quizzes using the math and real life data they’ve learned.
