Normal Distribution HyperDoc

I have found numerous normal distribution activities involving people's heights. I decided to take everything that I have seen and create a HyperDoc. Before this activity, I had not discussed normal distribution. This was an opportunity for my students to investigate and discover on their own.  

Before I shared the HyperDoc with the students, I presented the first slide: 
I had the students measure heights (inches) of each group member. Using painter's tape, I created a huge number line where the students stood by their height - thus creating a human dot plot. It was a little tight - I should have spaced out my tick marks a little more. Oh well, there's always next year. :) I mainly did the human dot plot to cancel out any errors while measuring. Some of my students were a little off and this corrected the issue. 

I had a blank dot plot on the board where students had to plot their height. I made them take a picture and place it on the HyperDoc once they grabbed a laptop. While the students were completing the tasks, I walked around allowing the students to explore and create their own frequency table and histogram using Google Sheets and the hyperlinked tutorials. This provided a little review from the previous unit and allowed students to get a sense of the data. 

Students were able to explore normal distribution by watching an EdPuzzle video. Once finished, I had the students create a normal curve using the mean and standard deviation from our data in the dot plot.
My favorite part - students made predictions using the normal curve:  

After predictions, the class found the range of heights that fell within 1,2, and 3 standard deviations of the mean. Using the dot plot, each group also had to calculate the percentage of heights that fell into 1, 2, and 3 standard deviations of the mean. They compared the results to their predictions. 

The last slide contains a video describing normal distribution and the 68, 95, and 99.7 rule. Even though one class was close, we were able to discuss why our data wasn't exactly normal! 

This is the first year that I have tried this activity, and I loved it. I prefaced the class by saying, I'm just here as a facilitator - I'm not teaching you how to do this. You must use your group members, the videos, and previous knowledge to complete the task. I did have to assist some groups more than others, but that was expected. However, I tried to answer questions with questions! :)

If you would like to try it or alter the activity to make it your own - here is my HyperDoc!

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 ...
