Polynomials: Finding Zeros Drag and Drop

Have you ever created an activity- spent HOURS making it perfect- and completely messed it up in front of the students? That's what happened to me with this Polynomials Zeros Drag and Drop. Oddly, it turned into one of the best days I've had with this class!

Here's what went down day of the activity: I sent the students the wrong link. Of course. Instead of sharing the student version, I sent them the teacher version. It was heartbreaking! The sweet kiddos told me the answers were already on the slides. I panicked (slightly) and tried to correct my mistake, but you can't unring a bell! So we went with it.

Luckily, my students are used to showing all of their work, and they did. It was actually pretty nice that they could check themselves as they worked. And they worked. I was truly amazed how much effort they put into this assignment.

The activity itself has students solving polynomial functions for zeros- in whichever manner they can remember. Because of Desmos, almost all of them plugged the equation into the graph first, and then used synthetic division followed by the quadratic formula to find any remaining complex roots. It went very well.

My colleague, RJ, used this as well. However, she teaches honors so there are some slight differences in the two versions.

Good 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 ...
