5:14 PM | Great Sam Shah Action
Sam Shah’s blog has been a veritable teaching clinic the last two weeks, more than filling his own installment of Great Classroom Action. With Attacks and Counterattacks, Sam asked his students to define common shapes as best as they could – triangle, polygon, and circle, for instance. They traded definitions with each other and tried to […]

2:51 PM | This week’s top new iPhone app is helping kids cheat on their math homework
This week’s top new iPhone app is helping kids cheat on their math homework: Daniel A. Medina: In response, the company wrote a blog post Thursday addressing the concerns—essentially saying that students looking to cheat would cheat anyway, with or without PhotoMath. They said they saw PhotoMath as a sort of 21st-century calculator: “We’re sure that the same questions were raised when calculators entered classrooms,” they wrote. “With PhotoMath, our goal is to make a much more […]

6:24 AM | How it Must Feel
Imagine yourself as a student who has always had a hard time with math. Honestly, you are not even sure why there are sometimes multiple variables in the same formula. When the teacher starts a new topic, you may need to see it 4 different ways and have it be repeated a lot of times in order to become somewhat proficient at the skills involved, even though the general idea is sometimes (not always) accessible to you. When other people discuss mathematics in groups, the speed at which they are […]

5:56 AM | Just because you use video doesn't mean you've flipped your class. And just because you don't like the "flipped classroom" doesn't mean you shouldn't use video.
Long title. I know. It's late and I couldn't think of a shorter one.  Think of it as a title/thesis statement all in one.~~I am finding more and more that people in education use the word "flip" to refer to anytime students watch an instructional video.  That's frustrating to me.For me, flipping my classroom was aboutfinding a way to support my students more in their learning, and tobetter differentiate my instruction and time with them.  It was aboutgetting out of the front of […]

2:21 AM | Polygonal Numbers
I just finished up arithmetic series, and I wanted to push my Advanced Precalculus students to think hard. I usually provide them with enough scaffolding that I know they will be able to get from Point A to Point B. But today I decided I wanted to “be less helpful.” I told the groups to […]

*The image is a pumpkin carved a few Halloweens ago by Sonja L. One of my Stats/Calc students (and a really good Bassoonist, Bassooner, Bassoon-enough)It is true that a mathematician who is not somewhat of a poet, will never be a perfect mathematician. ~Karl WeierstrassThe 304th day of the year; 304 is the sum of six consecutive primes starting with 41, and also the sum of eight consecutive primes starting with 23.

11:54 PM | A Frenzy of Marking: 'Progress Over Time'
The first half term of the school year has seen us embark on a newer emphasis on 'progress over time' and a need for students' exercise books to be glistening with not only marked work, but 'learning dialogues/conversations' including students' responses to our WWW/EBI comments. This, is also (as I found out in an observation the last week of the half term), coupled with students needing to show knowledge of their previous learning when quizzed during the lesson observation by my observers: if […]

11:48 PM | Why the Chess Computer Deep Blue Played Like a Human
Why the Chess Computer Deep Blue Played Like a Human: David Auerbach: The usual way a computer plays chess is to consider various move possibilities individually, evaluate the resulting boards, and rank moves as being more or less advantageous. Yet for games like Go and Twixt, this approach breaks down. Whereas at any point in chess there are at most a couple dozen possible moves, these games offer hundreds of possible moves (thousands in the case of Arimaa, which was designed to be a […]

10:04 PM | Halloween nel nome della chimica: effetto... spumeggiante!!!
Anche se non è una ricorrenza italiana, Halloween può diventare un'utile occasione per imparare qualcosa di nuovo a scuola ed acquisire un po' di manualità. Abbiamo visto, qualche anno fa, le opere d'arte matematiche realizzate con le zucche dagli studenti del dipartimento di Matematica della Denison University a Granville, in Ohio, utili per realizzare divertenti attività interdisciplinari tra matematica ed arte, ma quest'anno voglio proporvi qualcosa che abbia più attinenza con le […]
