Math from My Little Pony

Dr. Christine Alvarado, a science professor at UC San Diego, on how playing with My Little Ponies moved her toward math and engineering:

When I started, I took the hair on the Pony's tail and divided it into three pieces for braiding. Soon I became bored with a single braid. I then divided the tail into nine pieces and made three groups. I braided each group of three until I had three braids, then took these three braids and braided them together.

Soon I was up to starting with twenty-seven pieces (nested down to nine braids, then to three and then one) and then on to eighty-one. All the while I was learning about math: I saw that division is the process of taking a large number of things and grouping them into a smaller number of groups. In order to end up with one even braid at the end, I had to be able to divide the initial number evenly by three, then by three, and then by three again, until I ended up with just one braid.

The day after that page was made, I took a photo of some of my daughter's ponies, to use as an illustration at an announcement post, Sleep, Teens, My Little Pony & Science.

Holly, 18, had been away from the house. She came in and saw the ponies out, so I showed her the photo and read her a bit of the Christine Alvarado article. Holly got another pony to show me, told me about the plan of the braids and the angles to get them to cross and stay crossed, and what could be done with those braids, but that she usually twists them into a bun, and had left some unbraided hair out at the bottom of the mane to fasten that bun up with.

I couldn't even keep up with the explanation. Just sayin'... 🙂

Three children

Writing from early 2002,then 2012:

And now I have three children who are 10, 13 and 15. They have never been to school. They have never had a math lesson. But today Holly asked me to help her with 7/18 plus 5/18, for a video game she was playing. Kirby has a job and will do his income taxes soon for the second year. Marty was discussing odds and probability earlier with three other teens and his little sister.

Ten years and some later, Holly's about to turn 21, Kirby has done his taxes for years, and all three have taken math classes as young adults, for fun.

Sweetness in teens

Once upon a time, in 2006...

A story slightly involving allowance, but a snapshot of how kids who aren't desperate for money can act:

Two of Marty's friends were going to pick him up to go run around, but they ended up staying here. Then another friend came over to see all my kids. Then a friend of Kirby's from work came over. I hadn't met her before. She was nice. So my three (14, 17, 19) plus four more (17-21) were all having a great time laughing and looking at stuff on Kirby's computer and around our house, and Marty's big Lego Viking village, and so forth.

They decided to go out for ice cream and then to see "Over the Hedge." I asked Holly if she needed money, and she didn't. (She saves her allowance up.) Every other person there has a job. Outside of Kirby possibly having an interest in the girl from work, there were no couples. Two of those kids do have steady others, but didn't bring them over. So it was four teenaged girls, four teenaged boys, no romantic tension (unless Kirby and new-girl; didn't see any).

And here's the big success part. They asked Keith if he wanted to go. I didn't know they had, when Marty came and asked me if I wanted to go. So they would have taken me, or Keith, or both of us, with them.

We separately thanked them and declined and found out later they had asked us both. Pretty sweet!

We didn't "teach them" to invite their parents to the movies. One advantage of our not going was that then they could fit into the big van and didn't have to take two cars.

I posted this story in 2006 when it was six years old.
Now it is eleven years old. Our family looked like this, when the story was new:
