### Algebra 2: Power Equations

I had a great Friday. My Algebra 2 classes went well, though the Keynote took about 10 minutes longer than I wanted. But, the slide where I showed them how you can use the Pythagorean Theorem to locate root 2 on the number line was quite successful (I think). They agreed that we could construct the original square out of a 1' x 1' piece of wood. Then, after we use the compass to map out the length of the diagonal, I showed that we could cut a piece of wood that is exactly root 2 feet long. I'm really trying to drive home the idea that irrational roots are still real amounts, and this slide made their brains hum.

On Monday, we will be solving power equations in Algebra 2. Nothing too fancy, but we will be doing Showdown for the first time - one of my favorite collaborative activities. Here are the files:

I am really interested in what you're doing with your kids. I don't have much experience teaching and mine are a bit younger (middle school) but I seem to gather that most of your students are non-native speakers of English.
I'll keep track of your blog :)
