Guess the Heights: an Intro to Bivariate Data

While there are many introductions to this unit, I wanted to create something that was more fresh than the activities I have done in the past. Hence, I Googled. I found an activity similar this one, but it cost money. So, I spent about 30 minutes creating my own!

I have always avoided using the "Guess the Age" of celebrities since it changes yearly... but heights don't! Here is a link to my presentation; feel free to copy and edit according to your tastes and your students' interest.

I also forced a copy of this spreadsheet to my students. This way they could copy/paste their data into Desmos. This was pretty fun, I may want to add a couple more celebrities the next time I try it.

I also had everyone save their graphs in Desmos so that when the "Achieving Linearity" component of this unit popped up, everyone could choose their best fit model based on residual plots and numerical summaries. 

It was fun and little more updated than some past intro activities I…

Systems of Inequalities: A Desmos Activity

This is one of those activities that had all students engaged from the moment they logged in! 

Students begin by practicing graphing systems of inequalities and finding points that exist in the feasible region. Then students are asked to create a system with a specific point in the solution. They had fun playing around in Desmos and the ease of use within in website where they could clearly see the effects of changing values in their inequalities to fit the guidelines and expectations of the exercises.

Once the students were familiar with graphing systems of inequalities and finding solutions, we moved on to finding objects in a photo, this is point where the kiddos had the most fun. First, they graphed inequalities to see which object was isolated in two different photos. Then, they had to find Waldo and isolate him using a system of two inequalities. Finally, they were given a map of the US and asked to isolate North Carolina using three inequalities.

Crazy in Love: How to Sample

I saw this on Stats Medic (if you haven't visited this website and you teach AP Statistics, it's a must) and I'm so glad I tried it :)

I did this as my opening day activity, so the students have not had any prior AP Stats instruction and it's perfect. 

Basically, students "randomly" choose words from Beyoncé's "Crazy in Love" song, count the number of letters in the words, and find the average. We then make a class dotplot of everyone's means. Then, I show them how to use a random number generator (AKA their calculator) to choose a for reals random sample. Again, the students find the average word length and plot the result on a dotplot beside the first one we created.

Of course, we discuss the differences between the two dotplots and the importance of random sampling. We then decide, based on given information, if Beyoncé wrote the lyrics for "Crazy in Love". Oh yeah, I created a Beyoncé playlist to put us in the mood!

While I did tak…

Stats HyperDoc

We love hyperdocs! We force a copy which will automatically save to the student's drive. Once finished then they can share with us! It is so easy to grade! 

This activity involves a Desmos investigation that we found online. The link at the bottom of the page is the one that we edited because of time constraints. However, the one linked above is awesome! It goes through a couple of scenarios about sampling penguins.

Then students move through sampling techniques with a coloring activity. They must change the background of each cell with the correct sampling technique. 

The next section consists of data collection. Students must determine whether the data collection technique consists of a survey, an observational study, or an experiment.  Students then move to answer questions about margin of error and confidence intervals. 
The last portion allows students to design their own study. This allows the kiddos to be creative while explaining their reasoning! 
Here are the resources needed: 

Writing Equations Sine & Cosine Drag & Drop

Looking at the released NC Math 3 questions, I saw a trig drag and drop question. Well, why not let the kiddos practice some drag & drop by writing sine and cosine equations? This is very
easy to grade, and the students actually enjoy it! 

This was made for my Honors Math 3 class. I pushed them much harder than I would have an on-level class. I went past the curriculum and did phase shift since I know that they will see it again in PC. 

So, I forced a copy and sent it to my entire class. The best part, they just share it with me they are finished. I did have a little anxiety since I had so many unread emails in my inbox, but it really didn't take too long to grade. So crisis averted. (Haha) 

If you want to try it out, here is the student & teacher edition: 
SE Trig Drag & Drop
TE Trig Drag & Drop 

My colleague made one for on-level. I'm sure you will see that sooner than later! 


White Walkers: Exponential VS. Logistic

Finding an activity dealing with logistic functions was not an easy task. So what should we do? Create our own HyperDoc, of course!

While we are not Game of Thrones watchers, it would seam almost everyone else is so we decided to do a little research and instead of the zombies for most of these types of activities, we went with White Walkers. If you have no idea about these, don't worry- apparently high school students have no clue either. 

Students will need computer access to plot using Desmos, Google Docs, and Google Sheets- to upload an already created data set into Desmos.

This activity begins with randomly selecting one student from the class using a random number generator. This student will infect one other student (randomly), those two students will infect one more each, so on and so forth. 

Once the class data has been collected, the students go through the HyperDoc comparing exponential and logistic functions considering carrying capacity. There are several different parts …

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! 

Here is the activity: Adding & …
