9:45 PM | Triangles, Toothpicks and Patterns
This was our visual pattern in Algebra 1 today.  They were upset because there were so many triangles. And so many toothpicks.  Which then means…there were so many patterns. But the way they saw it was much different than how I saw it.  So I listened. J: But where are you getting the triangles?  Here’s […]

7:54 PM | On Being An Expert
Think about anything you consider yourself an "expert" in - a skill related to your profession, a hobby, a category of trivia or knowledge. How did you become an "expert?" You probably have a certain acumen for learning new things related to your area of expertise, but ultimately, it came down to a decision you made at some point to seek and find knowledge about a topic. And then to do it

6:18 PM | Reflective Teaching: Day 5
Post a picture of your classroom, and describe what you see–and what you don’t see that you’d like to. This is how my classroom  currently looks.  It is fairly small this year, which is a big change for me from last.  I like that I still have tables instead of desks, and the fact that […]

5:49 PM | How to Create New Mathematics
How to Create New Mathematics? Most people don't realize they can create new mathematics. It's an amazing thing. Let's try it.. Our new mathematical object will be a list of two integers and we'll write it like this.. (a,b) where a and b are integers. Why do we write it like this? Because we're the inventors and we can do anything we want. Great, so we've just invented a new mathematical object. Of course, our invention is not much use unless there are some operations we can do with these […]

5:31 PM | Every Math Teacher in the World Should Do This...Right Now!
Yesterday, I was teaching students how to find the greatest common factor of two numbers. We start this lesson by using easy numbers to work with (like 10 and 14), list all of the factors, circle the common factors, then determine which of these common factors is the greatest. No big deal.Next, we moved on to bigger numbers (48 and 84), and it became much more challenging. Some students just don't know their times tables that well, especially past ten. 3×16 equals 48? Even I'm a bit sketchy on […]

5:30 PM | Shamer shaming
This post is by Phil Price. I can’t recall when I first saw “shaming” used in its currently popular sense. I remember noting “slut shaming” and “fat shaming” but did they first become popular two years ago? Three? At any rate, “shaming” is now everywhere…and evidently it’s a very bad thing. When I first saw […] The post Shamer shaming appeared first on Statistical Modeling, Causal Inference, and Social Science.

Back-to-school usually brings with it an open house for parents and guardians to come in meet the teacher and see the classroom.

4:43 PM | A song about a knot
Norwegian duo Ylvis have just released a music video about… well, essentially it’s about physical knot theory. It’s about tying “the greatest knot of them all”, the Trucker’s hitch. This is great! Knots looking cool in semi-mainstream media! A completely unrelated thing I’m chuffed about is that, a week ago, I broke my 2004 record of 550km […]

4:10 PM | Is it time for a retraction penalty?
The title of this post is the headline of our most recent column in LabTimes, which begins: As we write this in mid-August, Nature has already retracted seven papers in 2014. That’s not yet a record – for that, you’d have to go back to 2003’s ten retractions, in the midst of the Jan Hendrik […]
