Personalized Polynomials

I was recently collaborating with a group of NC Math 3 teachers, I truly learned a lot from them while working that project!

One thing that went across my computer screen during this collaboration project was the "Birthday Polynomial" activity. Sounds straight forward, right? Just use Desmos, right? "What could possibly go wrong", I asked myself. Well, many things went wrong.

For starters, almost all students were born in the same year and the graphs were hard for my students to manipulate. They also had an issue with all of the zeros (2003 was the popular year of birth). Needless to say, I put out many fires that day. I knew I had to revamp this activity, not ditch it, as there are a lot of great features and learning points (a little pun there).

Introducing the "Personalized Polynomial" activity. In this version, we go from a polynomial with a degree of 7 to one with a more manageable degree of 3- what we mainly use in class anyway. Students are asked to find zeros, turning points, end behavior, etc.

Give a try and have fun!

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 ...
