I was unsuccessful, so I just googled it. I am amazed that this standard has just poofed from existence. This bothers me to some degree as a math teacher. I think students should learn all about all types of graphs, because that is one area that they will encounter after they leave the classroom. I actually saved a pile of Times Magazines with amazing graphs in them over the years to use in my classroom. Now to see that those magazines can't be used?!?!

I believe that the state should just use the normal "old-fashioned" teaching. The type of educational system my parents received at my age. Even with english, it saddens me when I see people at my age or older than me who can't spell. When our school was taking the test I saw a page of another student who had spelled it "hapend". But anyway, the tests are ridiculously hard and should be saved for high school where it is traditionally taught.

Sorry. We have an epic disaster on our hands now, perhaps caused by people who don't really "get" math designing things. Trained as an engineer, I can tell you this will help kids actually understand how things work, instead of the memorization we all grew up with. I believe people don't like this because they don't like math. I am not an educator, but a business owner, saddened by the lack of ability to understand how to use numbers in the people I employ. It allows them to make financial mistakes, etc., and is a real life problem.

The much-ballyhooed first question says "as a fraction of the whole" which implies a scale of 0 to 1. The whole point of a graphical representation with equal scales is to be able to eyeball data and estimate. Subtracting 2 1/3 from 7 is the same as subtracting from both sides -- and one can answer that question WITHOUT actually doing any equation solving as the incorrect answer involves subtracting something outside the parenthesis from something inside the parentheses when, even if using something like PEMDAS, you know you can't do. Students are introduced to the cartesian plane as "distance" and "direction" from the origin in 4th grade, so the negative axis should not confuse. Whether the student does 1/3 x 108 or 108 x 1/3 doesn't matter for this question so it is CC appropriate, etc. etc. etc. Brian Boughtonhttp://www.blogger.com/profile/05710559212858722496noreply@blogger.comtag:blogger.com,1999:blog-6172532982347376290.post-72903177950153971662013-11-19T12:02:26.734-05:002013-11-19T12:02:26.734-05:00Why didn't Gates just give all schools in the ...Why didn't Gates just give all schools in the US new computers for every student in every classroom and the infrastructure to actually use them?

If you form the equation, it isn't quadratic. It's cubic, meaning that there ought to be three solutions.
