Have you ever thought about the fact that “modeling” in the Common Core is not only in the Standards for Mathematical Practice, but also is a content standard? I have to admit that I hadn’t really thought much about it until a colleague asked me how the two things differed. I immediately started researching to … Continue Reading ››
Why is 6 scared of 7? Because 7, 8, 9. A silly little play on numbers I know, but this was the response from my younger daughter when I asked her for some “fun math inspiration” for writing this article. Surprisingly, I was
inspired. I started thinking about number and logic puzzles and asking myself why … Continue Reading ››
I’m just back from the NCSM
national conferences in Indianapolis. I have nothing but kind words for the city and venues for the conferences. It is a wonderful location for a conference; additionally, I highly recommend the haggis at MacNiven’s Restaurant and Bar
on Massachusetts Ave.Continue Reading ››
Schools should use open-source textbooks rather than traditional textbooks.
That’s the case David Thornburg makes in a recent blog post on Edutopia
. Dr. Thornburg bases his reasoning on last month’s discovery by NASA
that a microorganism living in Mono Lake uses arsenic rather than phosphorous to construct its DNA. He is entirely right … Continue Reading ››
A few years ago I was out walking in a park, and I stopped a teenager, about 16 years old, to ask what time it was. He stared at his analog wristwatch intently for a few seconds, as if he were trying to solve a problem. Then he took a cell phone out of his … Continue Reading ››
I was taken aback when I saw that a theater was showing the Michael J. Fox movie, Back to the Future
, in celebration of its 25th anniversary.
My first thought was, “Darn, am I that old?” After taking my Gingko Biloba, my memory was successfully jogged … Continue Reading ››
The Common Core State Standards that came out in June 2010 include standards for each of grades K through 8, then one set of standards for grades 9–12. Not surprisingly, many adopters wanted guidance on how to implement the 9–12 standards. Achieve put together a team to map out suggested “traditional” and “integrated” … Continue Reading ››
One word comes to mind when I think about data and statistics: FEAR.
My own educational experience with data and statistics is not exactly stellar. I don’t remember learning it in high school (apart from mean-median-mode), and in college I took calculus-based statistics before finishing calculus. When I did come across statistics in school, it was … Continue Reading ››
Do you remember your high school geometry class? I sure do—and I remember it fondly.
Mr. Brooks was in his first year at my high school, and we thought he was kinda cool with his full red beard and professorial glasses. In the first five minutes of our first class with Mr. Brooks, he told us … Continue Reading ››
“Don’t just do something, stand there.” That’s a line Dr. Bill McCallum, one of the writers of the Common Core State Standards, used in his presentation at the California Algebra Forum in San Jose, CA, which I attended last week.
Dr. Bill McCallum, one of the writers of the standards, used the line, “Don’t just do something, stand there,” when introducing the Standards for Mathematical Practice. He described a how he uses this line frequently in his teaching and it immediately struck a chord with me.
