Breakout: Exponential & Logarithm Review

In Pre-calculus, we have done physical and digital breakouts. So why not combine both components for this review activity!

Students walk in to see a breakout box, computer, and a clue at their station. The clue directs the students to a hidden envelope hidden around the room (each group has a different location) which contains a flash drive with a video we created using PowToon. The video describes the mission with an embedded clue to unlock the box.

In the box, students find a directional key, another log mission, markers (taped with log and exponential equations), a flash light (with no batteries), and two more locked boxes. The students must answer the questions from the log mission to open one of the smaller boxes - this gives a hint to solving the equations on the markers. Plus - it has has the batteries for the flashlight and a hidden message with invisible ink explaining the order of the colors. The colors correspond to a directional key.

In comes the digital portion. We created a Google Form with a couple of missions. In the video, the ending gave a clue to visit our websites in case they needed help. We placed the link to the digital locks there.

The first digital lock leads to more digital missions where students must answer log and exponential problems correctly to move on to the final clue - a picture of piggy banks. This unlocks the last physical box where students can enjoy some candy.

In the past, we both reviewed using a PowerPoint - students worked on problems - we went over them. This year, we have tried to come up with creative review days. A breakout is one of the best ways to do that! The students have so much fun and don't even realize that they are reviewing. Plus - it's so much fun watching the kids run around, practice math, and collaborate!

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 ...
