Normal Curve Practice: Matching

Someone bequeathed unto me this activity years ago - I hate that I cannot remember who, but let's be honest - I'm lucky I remembered my pants this morning 😀.  

Because this activity was shared with me so long ago, I had to convert it to a Google Doc and the formatting may be slightly off.  Feel free to make a copy here and edit it yourself to make it perfect for you!

Here's the gist: students are given a pack of cards.  There are Normal distribution situations on one side and answers on the other.  Begin by mixing the cards (in case the previous class left them in order 😨) and placing them all answer-side up.  Students will turn over one card, complete the task, find the answer on another card, turn over that card, and repeat.  Clearly, if done correctly, students will end on the first card they chose. This is great in that students will immediately know if they are right or wrong - without me giving them feedback.  They work in pairs to solve these questions and talk through any issues.  Of course, I circulate for the duration and make sure all students are good to go!

The drawback? you may ask... This activity is strictly procedural.  It is not what I would expect on my assessments, nor what the AP Exam will accept ("bald" or "naked" answers).  But you may notice, the students were drawing their Normal curves and shading the appropriate area (a requirement from me).  What was missing is the context in the responses - but if the answers had context this would not be a very challenging activity!  However, this activity truly helps the students recognize when to use the normal CDF vs. the inverse normal distribution.

Good luck and thanks to that wonderful educator who shared this with me!

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 ...
