Epsilon-Delta: Conic Sections: Parabolas
I split the class into groups of two or three and gave each group a sheet of this graphing paper with one of the lines darkened (which is to be the directrix). I told the students to plot seven or so points that are equidistant from the point in the middle and the darkened line. We found a couple together, and then they were good to go for the rest. When I gave them the following definition, they were able to fill in the blanks no problem:

flippingmath | My flipped classroom journey!
I suggest that students watch the theory part of my video and take notes as usual. But once they get to my examples I encourage them, as long as they feel confident, to try the examples on their own. Once they finish an example they fast-forward to where my solution is and compare their outcome to mine. If they do not have the same result then they simply go back and watch the video to see where they made their error. The power in this has been amazing because the students are becoming active with the video.

Quotes of the Day
There was some confusion with the coloring because it appeared that the pattern would continue to be a series of identical-ish triangles. Like this:

But instead there was a funny block at the bottom all the same color:

(I can't figure out why this picture is sideways. Oh well.)
Here's the arrangement of the correct ones:

The best quote of the day was from a student who was looking closely at the correct triangle. "That makes sense... it would just be a giant fractal." YAY! :)
(And then another favorite quote from today, "Did you get my email? (Me: No.) Good, because I didn't sent one." Oh, teenagers.)

Post-Spring Break...
I'm trying to do some catching up on my Google Reader, so I thought I'd post some links that I enjoyed...
1. Lisa Henry added a CCSS page to her blog. It's much better than mine right now. :)
2. I saw this a few weeks ago but don't think I mentioned it. Dan Meyer started a website called 101 Questions. It's a take on the #anyqs convo on twitter.
3. Vi Hart vs. Sal Khan. Awesome. (If you haven't seen any of her videos, you need to. Go.)
4. Kate Nowak posted some videos that go through the majority of an Algebra 1 course. Wow. (Here's her description of why.) Our tech guru in my district would like me to look into the idea of the flipped classroom; these could be an amazing resource. Thanks, Kate!
That gets me through about half of what I haven't read lately. And I just realized that I promised the kids new seating charts tomorrow. Dang. I hate making seating charts.

This site provides countless books, films, plays, and television shows that all relate to specific math concepts. What a fabulous way to integrate math, language arts, history, and more! The site includes the title, year, and brief description. Teachers can browse by genre, medium, motif, and/or topic. Media include everything from comic books to plays to television series. Genres include historical fiction, children's literature, adventure/espionage, fantasy, science fiction, and more. Sixty-three fiction offerings are even available FREE (in their entirety) online! The site is still developing and frequently adds additional fiction titles. Students who enjoy fantasy will also enjoy choosing books from this site, since the author admits that not all math mentioned in all the books is "real" math!! The site allows teachers to search by keyword and also to browse new offerings in the compilation of titles.
