Confidence Interval Project

You may already be using this project on confidence intervals for means, "Read Any Good Articles Lately?"; if you use TPS4, odds are you probably do (too corny?).  I just find it very insightful into what interests my students have.  Sometimes, when I'm checking their article for appropriateness and requirements, I can't stop reading it!  And other times... I'm not very amused.

I have adjusted my project to meet more of my expectations and my students' needs, but I think it is pretty close to the original.  Here's the breakdown:


  • Students must find a long article online. (I used to make sure it was a "trusted source", but those readings were so boring.  I mean, The Onion isn't trusted, but it's hilarious!)
  • Then they must randomly select a paragraph (I require proof of randomization) and create a table or spreadsheet with the length of the first 100 words.
  • Students will create histograms and discuss the distribution- a great review at this point in the game.
  • Finally, they will create a confidence interval, interpret a confidence level, and investigate a "claim from the author".
I cannot think of any cons in using this as a project, but there are many pros!
  1. Students have the autonomy to choose an article that they find fun.
  2. I get to check that they are doing inference correctly since this is one of the first sections on this topic.
  3. Using spreadsheets early in their higher-level educational career will set up the students for success in college.  Google Sheets is very easy to use and intuitive for my kids.
  4. I am able to give them feedback via Google Slides and they can resolve my comments when making any corrections.

Try this out with your students if you haven't already, they love the collaboration and ability to choose their own topics (plus, it's educational)!

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

Polynomial Picture Project

Projects allow the students to show off their creativity and math skills! This one requires students to use Desmos to help create a polynomial function that fits a picture of their choice. As you can see with some of the projects below - the ideas vary immensely. Some of the students are very clever and others just use the McDonald's sign. However, each year, the students amaze us at what they find.  Instead of using their calculators - here's how Desmos will find the regression line. In my video, I just did a simple quadratic, but our students have to create a regression equation that requires at least 3 relative extrema.  Typically, we show the students how to use the Desmos regression option before sharing the project. Some students have trouble fitting the graphs because they choose too many points, and others are upset that it doesn't fit perfectly! We reassure our students that this is the best fit - not a perfect fit.  Once students have the reg...

Logarithm & Exponential Concentration Game

Lecture is inevitable, but I like to divide up that time with small, hopefully fun activities. We all need a break from time to time, including ME!!!  I found this activity here , and instantly loved it. After explaining how to rewrite logarithms and exponentials, this game provided students with the perfect practice.  Just like the concentration game, students place all cards face down and then flip two cards over. They look for an exponential and logarithmic pair. If they find a match, YAY! If not, they have to turn them back over and lose their turn.   This is a fast activity; it took my kids about 15 minutes. Even though it was short, I think the students enjoyed not having to listen to me for the entire class! I'm okay with that; I enjoyed taking a break from talking!  :)  I could have cut out the activity that I found online, but I am a little OCD when it comes to fonts. So, I created a new version using the same problems. Here it is: Concentr...
