Day 5: Lesson Plans?

Well, that didn't take long!

Something about the best laid plans...

I managed to fall behind my lesson plans already.  To be fair, our schedule has been messed up by having early dismissals from the heat.  I was also reminded that I have a tendency to ramble when I find an interesting topic.

In geometry, we were defining terms, specifically points, lines and planes.  We were talking about what it means for something to be three-, two-, one- or zero-dimensional. I was reminded of one of my favorite ideas in geometry, which is that two-dimensional objects (like squares) can be seen as the projections or shadows of three-dimensional objects (like cubes).  Similarly, one-dimensional objects can be seen as the shadows of two-dimensional objects.

Extracting from this, it's a great way to ask students to visualize that they (three dimensional objects) are merely projections of some other four-dimensional object.

"Mr. A, what's the highest level math class you can take?"


In other, more reflective, news, I'm having difficulty realizing that my 3rd period class is my 3rd period.  I keep thinking it's 4th and I keep getting shocked when kids come after they leave.

No worries though. I have 175 more days to get it right.
