At my recommendation, one of our all-faculty reads this summer was Make it Stick, which means that hopefully the language of the book will be buzzing around our school a bit. I really want to jump on that; I’m spiraling homework and assessments in all classes this year, in response to the book and CPMRead More

## Posters. WHAT??? Team roles.

My first three years of teaching, I had my own classrooms. And my school had a thermal poster maker, and really big rooms (with 16 foot ceilings!) So I made a LOT of posters.For the last seven years, however, I’ve shared classrooms. And my poster-making has faded to essentially nothing. This year, for the firstRead More

## Programming for Statistics

CPM makes textbooks that live on paper, but in AP Stats we are taking the leap and assuming that most classes have access to at least a few computers for demonstration and exploration. So what does this mean? Stats applets! Most textbooks come with a series of statistics applets that help demonstrate concepts. For example, appletsRead More

## Starting a project

Writing for the CPM AP Statistics text started with a week at a Homewood Suites in Minneapolis right across the street from the Mall of America. I didn’t get out much, other than when I got to eat dinner with @VeganMathBeagle and @trianglemancsd on my first night and one night out with the whole writing group.Read More

## Summer of Statistics

I have not blogged much this summer, partially because I’ve been working. Working hard. On this: Yes. CPM, the creator of the student-centered geometry book that blew my mind, is creating an AP Statistics book. And I’m helping to write it. And, having complete control over the AP Statistics curriculum in my school, I’m also usingRead More

## My AP Statistics Review technique this year

I teach at a school of pretty extreme go-getters, and I decided to embrace that for my review period this year in AP Stats. Rather than do too much review together, I decided to base make review a primarily self-directed affair. They are required to complete three different things by the AP Exam, at theirRead More

## Goals for next year, so I can stop thinking about them right now!

Yesterday I tweeted this: This time of year I have to fight the temptation to cut my losses and start living for next year. I Find self-doubt easy in April. — David Griswold (@DavidGriswoldHH) April 8, 2016 So today I’m writing this quick blog post for myself to help me get it out of myRead More

## Trapezoid Formula Jigsaw

Today in class I tried a new activity I made. I had a lot of goals for this activity: Show that triangle midsegments are parallel to the non-touching side and are half the length of the non-touching side. Show that trapezoid midsegments/medians (I hate that my book calls them medians!) are parallel to both basesRead More

## #MTBoS Critical Friends Group

I have been reading about using the Critical Friends Protocol for improving teacher products (lesson plans, products, problem sets, whatever) and it seems really neat. The basic process is this: Critical Friends Process Presentation One person, the presenter, presents a product they would like feedback on. This can be anything. The presenter shows everything they haveRead More

## Infinite “Extra Credit”

I teach AP Statistics, which I find to be an incredibly challenging curriculum. I have a very heterogeneous group of math confidence levels (students who took Algebra II as juniors up through students in multi-variable calculus taking this as a second math), we do almost no probability and statistics in our earlier curriculum, and, frankly,Read More
