- Here it is, more of the same, this time in a weekly format, which both the author and the readers might find more manageable.
- It has always been the goal that I reuse every minute I spend working on school outside of school. Yeah, I spend ample time revising but I’ve never made a worksheet or a lesson plan that wasn’t waiting for me the next year in some kind of digital storage. If anybody else gets anything out of these, it’ll make my time feel even less wasted.
- Please comment. Nitpicking (“those figures ain’t drawn to scale”) will receive a polite “thanks,” a revision for future drafts, but little else. Substantive critiques – alternate methods, exciting investigations, effective strategies – will receive a lot of gratitude.
- We didn’t touch a syllabus the entire first week. I alluded briefly to my two big-time class rules (respect the speaker, always participate) but didn’t go near my usual enforcement methods (the one minute board). I have no idea what this means, only that it’s potentially paradigm-wrecking, something that circles issues of positive expectation and the teacher-student relationship. I’m confused.
- The protractor on day four kinda swoops in under the angle. Some kids thought that was pretty cool.
I’m greeting at the door. They come in and something is waiting for them. This sets the year off right as far as I’m concerned.
We use the instructions laid out on page 39 of the attachment. Offer them one homework or the other: hold up a stack of handouts or tell them they have to make the icosahedron. As they’re pondering their options, start the timer. Freak out time.
Michael & Jessica
We’re laying the groundwork for geometry right here. Setting ourselves up so we can talk this language.
Talk to a neighbor, a friend, a loved one, or yourself. Give us two examples of points, lines, and planes.
Which tennis balls are coplanar? Which sets of three are collinear?
You wanna say that two segments are congruent, you mark it in with cut marks. You wanna KEEP saying that segments are congruent, you keep on marking it up.
Free food for life.
Ask people to tell you what the points are. Ask them to put down what looks to be about the midpoint. Write the coordinate down. Decimals are okay.
Have them notice that it’s two over, three up, two over, three up.
Referencing a slide from earlier in the week. Again, we’re laying foundation so we can talk about shapes and figures.
Talk about acute vs. obtuse here.
