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

AP Calculus Hunger Games Review

I created this a couple of years ago when Hunger Games was really popular. However, I thought that I would share with all of you in case you wanted to use or revamp to something newer.  I created 12 groups for the 12 districts. They decided what their name would be as a district. They had tasks each day to accomplish. The tasks were just multiple choice questions centered around the major topics of Calculus AB. This took a lot longer than I thought - about 4 days. I was forced to give them more than 15 minutes for each task (which did not make me happy since the AP exam is timed - Oh well.) I had the time, and it worked out.  You can decide how you want to the points to work, I gave them 2 points for each correct answer. It was very easy to grade as this is the student worksheet. They placed the letter of the answer in each spot.  I made them show all work on another student sheet so that I could see what we needed to review.  Each day, I would ...

Adding & Subtracting Rational Expressions Drag & Drop

Because Math 3 now has drag & drop on the final exam, students need the practice. So, I created one using Google Slides. It went over really well!  While this only took the students about 40-45 minutes to complete, it took me about 2 days to create this activity. Oh well, at least it is cute! :) I used Google Drawings to create the scene and took a screenshot of the drawing to post as the background in Google Slides. This worked so that students could only move the answers.  I created this for an Honors class and one of the problems (#5 - the one pictured) really stumped the kiddos. I loved it! They kept thinking that x - 1 was not part of the common denominator...they didn't realize that they needed to simplify after subtracting. It really made them think!   When they were finished, they shared it with me! I really think that this helped the kids get more practice on drag & drop while working on adding and subtracting rational expressions!...
