Skittles & Measures of Center

I'm pretty sure you have seen this activity before! It's nothing new. However, I gave it an updated spin using Google Suite. 

 I created a HyperDoc where students read an article and collaborate to complete a Google Sheet. The article claims that there are more yellow skittles in each package. Well, we all know, since it is on the internet - it's true. šŸ˜‚ 

 Well, we decided to do our own experiment. I did spend some $ on this activity, but I ordered the skittles from Amazon, and feel that I saved some money that way. 

 I would typically do this in groups of 2, but I have a small class this year, and I wanted more data. I had each student count the number of red, yellow, green, purple, and orange skittles in each bag. I shared the Google Sheet so that each student could edit, and they typed in the data from their bag. I love using Google as a collaboration tool. 

Once all students were finished, I had them go back to the Google Doc and complete the table using the class data. I didn't tell them at first how Google Sheets could do all of these calculations. After the first color, one student was on a mission to figure out a better way - and used Google search!  

I know that this lesson is about the students calculating mean, median, and mode, but I feel like being able to use technology is just as important. Other students started to catch on, and finally the class was utilizing the explore tool in Google Sheets. I was so proud! (From formative assessment early this morning, I knew that all students were masters at measures of central tendency, so this didn't bother me!) 

 Using the data, the students answered questions on the HyperDoc and shared their copy with me. The class data showed that out of our batch of skittles - there were more orange skittles! This brings up a great discussion - is this always true? Does it have anything to do with our sample? What could we have done differently? What does the mean tell us about our data? Overall, I would say that it was a great lesson.

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 ...
