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've used. Plus, finding the heights of people is super easy!

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 ...

Arithmetic & Geometric Recursive Investigation

Investigation and student accountability is extremely important in education today. Students need to be challenged! They will learn so much more by discovering the formulas rather than me just placing the formula on the board! While talking to my intern about not finding anything cool dealing with recursive sequences, I got an idea. I wanted my kids to find a pattern and develop the arithmetic and geometric recursive formulas using the information that they already know. I created a cut and paste activity where students had to match the sequence, the type, the common difference/ratio, the explicit formula, and the recursive formula. From that, I hoped that students would be able to see a pattern! On a note card, I had them answer three questions...describe any patterns that you see, write a general recursive arithmetic formula, and write a general recursive geometric formula. The students did an awesome job until they were asked to produce the general rec...

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
