My most recent post, about math mentors and math fun, was the 25th on this blog. The calendar year is about to turn; I’m a little less than halfway through my year to think it over. Time for a mixed salad of quick thoughts, including some resolutions.
More math fun
First, it turns out that 2013 is not prime. All year I’ve wondered. Finally, this morning, I started scratching calculations on the back of an envelope. Then I went to the web to double-check, and found a prime factor calculator. That confirmed it, just in time:
I also checked 2014. That, too, is a product of three primes, but I’m not telling. (You know right off the bat what one of those primes has to be.)
After reading the previous post, Kate Keller said some really nice things, including, “Wait! You left out the birthday ritual!”
Kate’s remembering something we did whenever a birthday happened in my class. I started by writing the child’s new age on the big whiteboard: 11, or 12, or occasionally 13. Then I’d ask, “What can we say about the number —?”
Students responded in a variety of ways:
- with cultural uses of the number. (“It’s a dozen!”) (“Some people think it’s unlucky, but they’re crazy…”)
- with expressions that equaled the number: 3 x 4 = 12, or 14 plus -3 = 11, or much more complicated expressions coming out of our experience with Lloyd’s Game (described in the previous post.)
- with a magic number sequence that started with the number and returned to the number.
- with words that describe other properties of the number: it’s odd (or even); it’s prime (or composite); it’s a palindrome; it’s deficient or abundant or perfect.
These various statements, written on the whiteboard, both documented learning and provoked it. Although we focused on the same numbers again and again, the activity was repetitive only in the way ritual has to be repetitive: a pattern similar in every iteration, but never actually identical; a shared dance in which roles can change and change again; a bowl or basket or web for both familiarity and innovation.
If I forgot to include the number ritual in our celebration of someone’s birthday, or if we ran out of time before dismissal, the kids insisted that it be carried over to the next day. Remembering my students’ affection for the ritual, and remembering the way every student participated, I feel like I’m holding some important key to who they were, and are; something hard to put into words; a treasure.
For still more math fun, check out the YouTube channel of Vi Hart. Here’s a link to one of my favorites, the first in a sequence of three about plants and the Fibonacci sequence. “Ow!” one of my younger students said. “My head hurts! Play it again!”
More My Place
I’ve been tickled to have the posts about My Place get a steady trickle of hits from Australia, so I did some behind-the-scenes backtracking. In the process, I found a wonderful collection of material relating to Nadia Wheatley, with an author interview, curriculum plans, and reviews of some of her other books–and a link to my own post about My Place, down towards the bottom. Great stuff!
If I were teaching right now…
I would read aloud The Higher Power of Lucky, the first in a series of three novels about a girl named Lucky in a town named Hard Pan, in the Mojave Desert.
Living in a very small town, Lucky has memorable friendships with both kids and grown-ups. She eavesdrops on twelve-step anonymous meetings, hoping to hear the advice she needs. She hopes seriously for an afterlife, because there are some questions she would like to ask Charles Darwin. (She has a dog named HMS Beagle.) She’s cranky and impulsive and imperfect and worth a million dollars, and she’s part of a new sub-sub-genre of realistic contemporary fiction for young adults, in which characters think about biological evolution and what it means, and interact sympathetically with adults who can’t or won’t.
“If” thought # 2: I would figure out how a class could use the latest book by Alice Roberts, the charismatic anthropologist and medical doctor who narrates a BBC video series (which we did use in class) called The Incredible Human Journey.
Alice’s new book (we pretend to be on a first-name basis with her, in my household), published by Dorling Kindersley, is called Evolution: The Human Story. It uses narrative, model reconstructions, photographs, illustrations and charts, to take the print medium’s slower-paced (but thrilling) look at the history of our species, starting with the Big Bang. Such a rich resource for a class to use!
A third “if” thought: I would explore the idea of privacy, which matters a lot to 11- and 12-year-old people, and keeps coming up in the news.
One of my most faithful readers wants to know why I haven’t yet written about some teaching and learning that was central to my teaching life:
- about the evolution of life in general, and about human evolution more particularly;
- about animal behavior and archaeology and the history of technology;
- about immigration, both chosen and involuntary, in the history of our country and our communities and families;
- about Islam and the Arab world and the history of Arab Spain;
- about The Voyage of the Mimi, both the first and the second;
- and about the making of Voyage to the Sea.
Instead of writing about evolution, I guess, I’ve been evolving. (I know; I’m using the word in two of its different senses.) Somehow I’ve had to work up to those topics, and also work down with them. They’re all so huge for me, giant human artifacts around which I’ve spent all these years crawling, like an ant in the jungle, climbing up and looking around whenever I felt brave, or whenever a student was nudging me onward.
However, I’ve just made that list. I’ve included some of it sideways, in this mixed salad post. I’m pledging myself to figure out ways of exploring those giant thoughts in 1000 word packets, before my year to think it over is over.
I welcome, and probably need, suggestions from readers who shared those themes with me as student or parent or colleague or cheerleader. If you were writing this blog, how would you tackle all that big stuff? Just askin’.
In an activity so solitary (except for the joyful throng of co-conspirators in my memory), tiny encouragements from the rest of the world mean so much! A quick note in an email, a side comment in the aisles at Colella’s, a post on a website generated on the other side of the planet, devoted to a much-admired author–each of these remind me that I’m really doing this, and parts of it matter to other people. Some of you have recommended the blog, or a particular post, to friends and relatives and colleagues, or on Facebook; some of you have written comments on the blog itself, invariably thought-provoking, nudging me and lifting me forward. For all that…
Recently, my daughter has been sharing a website or movement called Lean In, which encourages women to lean into their ambitions, to overcome fears and take risks, with each others’ support. I take a big breath and “lean in” every time I publish one of these posts, and I’m inviting you to lean in with me, women and men (and girls and boys)–whatever that may mean for you.
