Volume You Can Eat

When trolling through Twitter recently, I was reminded of a time when I taught Geometry... two decades ago.  Back then, I would do an activity where I would assign students a 3D shape and they would have to create an edible dish with it- almost always cake.  Because of the changing times, we are no longer allowed to have students make food to bring to class (a while back, a student actually brought laced cookies to school and gave one to her teachers; it was terrible).  Plus, I only taught Geometry my first 2 years of teaching- so no need for this activity... until now.  

 Because we are integrating Algebra 1/Geometry/Algebra 2, I teach volume and surface area again.  So why not bring back "Volume You Can Eat"?  It's quite simple, stock up on Little Debbie snacks (they're pretty cheap)- or anything else that works for you.  I like Little Debbie because it's easy to find cylinders and rectangular prisms.  I used chocolate balls for spheres but could not think of a triangular prism that's edible and individually wrapped.  Next, make assorted bags with different shapes of food, hand them to groups with this student sheet, and it's like magic... they immediately start working (of course, it helps that they aren't allowed to eat until they've found the volume for all items).

 My students were very appreciative and I was a little surprised the food didn't give them a sugar high- they stayed pretty chill for the duration of class.

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 ...
