I merged the study of triangle trigonometry and polygon area in my geometry class, since they go together very well. For their test, I created this multi-part area problem I like quite a bit. You can click the image to access the Geogebra sketch I used to make it on GeogebraTube if you’d like toRead More
I had a hard time coming up with a candy activity for bivariate data that was really good. I ended up kind of cheating, and wrote an activity that has students gather lots of data points, one of which is “how many jelly beans can you pick up in one no-palm pinch?” and then letting themRead More
Yesterday I did a chi-square goodness-of-fit test with my class comparing a large sample of M&Ms – over 800 of them – to the data that is provided by Mars for the true count of M&Ms. We got a p-value of 0.0002, which seems crazy. So now I simply need to know how accurate their dataRead More
As of now, I have written 3 AP Statistics review activities centered around candy. You can access them all by clicking here. They are taking us around 2 class periods each, which is a full 160 minutes of class time; not a short commitment by any means, but I’m enjoying the long game connections a LOT.Read More
Inspired by the general enthusiasm for the process in the MtBOS, I tried my first 3 Act Math Lesson(s) today. If this is somehow the first place you’ve heard that term, Dan Meyer has been the main force and originator of this structure, and I’ve also seen good explanations of the structure from Dane Ehler,Read More
The Great Geometry Soccer Goal project ended a couple of weeks ago just before spring break, and I’m finally ready to finally debrief. I already wrote many of my thoughts at the mid-point of the project, so this one will be brief. If you’re interested in seeing the products, here are the videos they made. TheyRead More
Today in AP Statistics we continued the Great Candy Review by comparing Starburst proportions to the skittles proportions; specifically, we started trying to decide if the proportion of orange starbursts could be equal to the proportion of orange skittles. The activity covers both 1-sample proportion tests (by assuming that 20% of skittles are orange, as weRead More
Spring break officially ends in a little under 12 hours, when my first class starts tomorrow. Naturally, tomorrow is the day in our rotating schedule where I don’t have a single free period, so it will be quite a change of pace. Having just finished up our giant soccer goal geometry project, I’ve given myselfRead More
Our geometry soccer goal project was scheduled for five 80-minute class days, but we lost a class day in every class due to snow. They were required to do some work on their projects at home during those days (we do “remote school” on snow days), but certainly not as much productive work was done.Read More
I am teaching AP Statistics this year, and, in general, really like it. I have a science background as much as a math background, so statistics is very appealing to me, and I honestly do believe that it is more important and useful than calculus for many, many people. Plus, I think it’s fun! MyRead More
