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!

AP Calculus Hunger Games Review

I created this a couple of years ago when Hunger Games was really popular. However, I thought that I would share with all of you in case you wanted to use or revamp to something newer. I created 12 groups for the 12 districts. They decided what their name would be as a district. They had tasks each day to accomplish. The tasks were just multiple choice questions centered around the major topics of Calculus AB. This took a lot longer than I thought - about 4 days. I was forced to give them more than 15 minutes for each task (which did not make me happy since the AP exam is timed - Oh well.) I had the time, and it worked out. You can decide how you want to the points to work, I gave them 2 points for each correct answer. It was very easy to grade as this is the student worksheet. They placed the letter of the answer in each spot. I made them show all work on another student sheet so that I could see what we needed to review. Each day, I would post the new rankin

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

Adding & Subtracting Rational Expressions Drag & Drop

Because Math 3 now has drag & drop on the final exam, students need the practice. So, I created one using Google Slides. It went over really well! While this only took the students about 40-45 minutes to complete, it took me about 2 days to create this activity. Oh well, at least it is cute! :) I used Google Drawings to create the scene and took a screenshot of the drawing to post as the background in Google Slides. This worked so that students could only move the answers. I created this for an Honors class and one of the problems (#5 - the one pictured) really stumped the kiddos. I loved it! They kept thinking that x - 1 was not part of the common denominator...they didn't realize that they needed to simplify after subtracting. It really made them think! When they were finished, they shared it with me! I really think that this helped the kids get more practice on drag & drop while working on adding and subtracting rational expressions!
