Matched Pairs: Breezeway Bowling

Matched pairs design is one of those inference topics that can be a little tricky for learners; many students want to try a 2-sample t-test for means. As an AP Reader, I remember a few years ago when paired data was on the National Exam. It was bad. So few responses actually used the correct procedure 😕

So if there's a way to get my learners to differentiate between these two types of inference (and make it stick), I'm going to do it!

I first found this activity on mathcoachblog (Hallway Bowling) and completely stole it from Bob Lochel- making my own tweaks, of course. My classes have over 30 students, so bowling in the hallway can lead to some major disturbing of other classes; therefore, I changed it to to the breezeway. Plus, I am lucky to live in a location where we can play (play = do math) outside pretty much year-round, so taking it to the breezeway was a no-brainer.

This activity is the first time my students will conduct an inference procedure with paired data. However, they have already been introduced to 1-sample inference for means. Feel free to view and copy my version of the template by clicking here. This document includes all instructions for the students and a lesson closing discussion that Bob suggests.

Polynomial Picture Project

Projects allow the students to show off their creativity and math skills! This one requires students to use Desmos to help create a polynomial function that fits a picture of their choice. As you can see with some of the projects below - the ideas vary immensely. Some of the students are very clever and others just use the McDonald's sign. However, each year, the students amaze us at what they find. Instead of using their calculators - here's how Desmos will find the regression line. In my video, I just did a simple quadratic, but our students have to create a regression equation that requires at least 3 relative extrema. Typically, we show the students how to use the Desmos regression option before sharing the project. Some students have trouble fitting the graphs because they choose too many points, and others are upset that it doesn't fit perfectly! We reassure our students that this is the best fit - not a perfect fit. Once students have the reg...

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...
