Dating Game: An Introduction to Scatterplots

A good friend of mine, Erica Chauvet (here is a great article about her), shared with me this activity.  As with most of my AP Statistics friends, I met Erica at the AP Reading many years ago.  Have I told you recently how much professional development comes out of the Readings?  If you have not yet done so, apply with College Board to be a Reader!

Okay, off of my soapbox...

This activity can actually be used at any level of learning scatterplots.  If you teach beginning linear regression, this would be great as a closer.  Of course, I teach AP Stat so I use it as an opener.  As a matter of fact, I give zero instruction on bivariate data before giving this out and the kiddos jump right in and start plotting and such.

For the random pairing component, as always, I demonstrate proper techniques to my class.  Sometimes, I put the student names in a "hat" and draw out two at a time - those will make a pair - and I continue until the "hat" is empty and everyone has a partner.  On this particular day, I used the random number generator on my Google Sheets (it's an add-on).  I pulled up my spreadsheet of student names on the projector, randomly assigned each student a number 1-30 (you know, because I have 30 students in this class), and sorted the numbers.  The partnerships were  students 1 & 2, 3 & 4, ... , 29 & 30.  I like to randomly pair so that students get out of their comfort zone and build relationships with new people.  Come to think of it though, I'm pretty sure none of my students have actually gone on a date after this activity.  Perhaps you'll have better luck!

Exponential Growth & Decay Scavenger Hunt

Scavenger Hunts are always fun (and easy to grade). This particular one is all about applications of exponential growth & decay. My students seem to understand this topic really well, but I still wanted to provide more practice.  When I did this hunt originally, I created the cards with the answer on the front and the question on the back. Once I figured out how to copy and make it work, it was great because I could use the cards over and over again. However, they started looking old, and I lost some of the cards. So t his year, I placed the answer and question on the front. It made it so much easier to copy!  If you would like to try this in your class, here is a copy ! I included the solutions as well.  UPDATE: I created this activity and transformed into a remote version.  Remote Version: SE Scavenger Hunt               TE Scavenger Hunt ~RJ

Modeling Exponential Growth (M&M Activity)

I could present an application problem on the board, have the students plug into their calculator and find the exponential regression equation. However, I think that visualizing the growth is more effective, and allows students to see how fast something like cancer cells can grow. This activity provides a hands on experience with M&Ms while modeling real world concepts.  I found this activity here , but created my own (slightly different) version. I only had enough time for exponential growth, so I eliminated the decay portion.  I really like how students compare the equation that they found to the calculator's regression model. This activity also causes students to discuss each component of the equation, which I think is very important in AFM. Additionally, this brings up a great discussion regarding cancer cells. Do all cancer cells grow exponentially? If time allows, I like for students to do some research (using their phones) to aid with this conversation....

Limit Project

Well...we just got back into school after being out for almost 3 weeks because of hurricane Florence. Our school is okay, but there are many people out there suffering from losing so much. :(  I had planned on a project for Calculus before the storm but will have to put that aside until next year! We have just lost too much time. However, I wanted to still share the project with you guys in case you would like to try it or something similar to it.   I like to make projects a unique experience. I hate when all students do the same thing. #1 - students can and WILL copy. #2 - It's boring to grade!  The idea of this project is floating somewhere on the web. I honestly can't remember where I got the idea. But I have altered it over the years to meet the needs of my students. It has gone through many alterations, and I will continue to change things.  So it is not perfect!  The gist - students find a recipe that has at least 5 ingredients. (The recipe ...
