Wholesale whole-number murder and redemption

An extended mathematics metaphor:

Flowing under the pre-K through high school curriculum, like the ever-widening Mississippi, is a steady expansion of the number system and its corresponding basic operations.

Important milepost concepts and mathematical problems which are posed, deconstructed and solved throughout those years are like the flatboats and steamboats of Mark Twain's era which floated upon the Mississippi's waters.

One doesn't seek to control the river, because the number system and its operations exist in nature, but we can select what floats on it and where to travel.  Choosing when and how to introduce concepts, what problems to pose, and where they fit is the foremost responsibility of a standards and curriculum developer.

About the bloggers…

First, a pledge:

We, the bloggers, hereby affirm that we have a particular interest in improving K-12 mathematics education and will do what little we can to advance that worthy cause in the confines of this blog.

Since it is impossible to expound on all that is right and wrong with Common Core in one fell swoop, we can only address issues piecemeal, at the risk of occasionally sounding incoherent, or even worse, looking like bloviating ignorami.  We know that we may contradict ourselves at times.  Writing a blog is difficult; kudos to you bloggers out there.

We should interpose that we are not salaried educators, we are not political ideologues, we have no personal vendettas, we are not self-absorbed egoists, we have no children in school, and we have no pecuniary interest in the future success or failure of various educational reform efforts.  We are disinterested parties, and we are not selling any product or service.  We own no stock in any education-related publicly traded company.  (Did we overlook anything?)

Because we are unbeholden and free of conflicts of interest, we are able to speak truth to educrat-power.

[It is remotely possible that someone will want to hire us in some capacity to spiel on their (more heavily trafficked) website, so some of the previous statements may have to be superseded.  In the unlikely event that happens, we'll be sure to let readers know.  We believe in full disclosure about any financial or other potential biases.]

We have what we consider to be sufficient credentials to comment on the matter (and we'll let readers judge that statement based on the content of our posts), but we remain anonymous to let our words speak, rather than potentially being directly assailed or having our credibility questioned.  We wish to draw attention to the issues, not to ourselves.

Common Core: a national cop-out, not a national curriculum

A cautionary tale...

In the 1980’s, the combination of banking deregulation and lack of oversight allowed a breed of banks known as Savings & Loans to embark on a scheme of making risky loans using depositor funds.  If the loans worked out, the S&L’s stood to profit, but if the loans failed, the deposits were insured by a federal insurance company (the FSLIC).  For the S&L’s, it was a ``heads I win, tails you (the insurance company) lose'' situation.

But it was even worse than that.

When enough loans went bad (of course they did, otherwise it wouldn't be a story), the FSLIC was depleted and went bankrupt, taxpayers footed the $100 billion bill, and (although we are not presenting the entire history lesson) these events contributed to an economic meltdown that is commonly known as the ``S&L crisis''.

What can we learn from history?  For us, it is when someone hands you a ``heads I win, tails you lose'' proposition, be very, very careful before signing on the dotted line.
