Mathical

"It's magical!" a student said, after we found multiple patterns in a chart during math class.

"No," I said, "it's math."

"It's mathical!"

In class we're doing a lot with globes. My students can label the seven continents and five (yes, five) oceans, but going from a two-dimensional map to a three-dimensional world is a big leap. They have a hard time mentally wrapping the edges of the map around.

(Also, to them, the Atlantic Ocean is always in the middle, so next week I'll be having them label a map where the Pacific Ocean is in the middle, like so many of the maps I saw in Korea. I might even spring an "upside down" map on them.)

So we've cut out maps with twelve gores and put them together, and we've done origami to create a globe.

Today I gave the students outline maps of the continents and Styrofoam balls. "You're going to create your own globe," I said. "We're going for effort and attention to detail, not perfection."

Thirty minutes later, one of my students showed me his globe. "...and my South America sort of looks like a wolf with no eyes, no mouth, and no nose."

An American educator moves moved to Korea, presumably to teach English. Instead she discovers discovered that learning Korean one taekwondo class at a time is was a more captivating activity.

Somewhere along the way, she met a Good Man, fell in love, and ended up back in the States. Still doing taekwondo, still learning Korean...
