...Claimed to be from a 7-th grade pre-algebra book:<br /><br />A man is 3/8's of the way across a train bridge, when he hears the whistle of an approaching train behind him. It turns out that he can run in either direction and just barely make it off the bridge before getting hit. If he is running at 15 mph, how fast is the train traveling? Assume the train travels at a constant speed, despite seeing the man on the tracks.<br /><br />Taken from http://www.ocf.berkeley.edu/~wwu/riddles/easy.shtml<br /><br />This is what a real math should look like.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-81899572829812205372014-09-13T11:12:44.324-04:002014-09-13T11:12:44.324-04:00 A 4th grade word problem presented in 8th grade i... A 4th grade word problem presented in 8th grade is appropriate for the inclusive nonhonors classroom.<br /><br /> The issue is that honors may have been eliminated,so that the students who would have benefited from a more appropriate level, pace and depth have no opportunity at all.

The only thing you have to remember is to count Wendy in and know that there are 6 kids. The addition is the only thing you need to write down your work for. Since the items add up to $12.99, subtracting to get the change is trivial. Question 6 is stupid; all it is doing is asking you to multiply 6 x 2.<br /><br />The problem takes about 5 times longer to read than it does to solve, and the math content is negligible.<br /><br />It also could be criticized, I suppose for not telling the student which ingredients go into making s'mores. There must be kids out there who have no idea what a s'more is--I'm thinking about urban kids and kids in immigrant families.Auntie Annhttp://www.blogger.com/profile/05777983027361603449noreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-60221147403341078712014-09-05T11:10:11.020-04:002014-09-05T11:10:11.020-04:00It seems that anyone can be "inspired" b...It seems that anyone can be "inspired" by common core, in various ways.Hainishnoreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-54013880571605698262014-09-05T11:09:56.639-04:002014-09-05T11:09:56.639-04:00The answer to question 1 is given directly in the ...The answer to question 1 is given directly in the text.

I also found the introduction to proofs through geometry to be mind-expanding learning. <br /><br />But, though I share the lament, I also think that the "core" learning can't remain stuck in any point in time. As the world changes, we may find other things we need to teach that might even teach similar critical skills, that should function as replacements. For geometry proofs, and the logic and language that I value from them, programming and algorithms might be just as important. <br /><br />bjAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-19604395064350276822014-09-01T11:42:48.647-04:002014-09-01T11:42:48.647-04:00Geometry was always my favorite math class.

"Rate of change" is obviously a wordier stand-in for "slope". Has "slope" been outlawed in favor of new jargon? <br /><br />If you rephrased the question: "which has the greater slope", I think it would be a bit less ambiguous. My guess is that it was written that way originally, but they decided "slope" was too technical and went with "rate of change" instead. <br /><br />But they didn't stop to think that the words are not completely interchangeable. A "rate of change" can be great in a negative or positive direction. A line with a slope of -4 has a rate of change equivalent to a line of slope 4.Auntie Annhttp://www.blogger.com/profile/05777983027361603449noreply@blogger.comtag:blogger.com,1999:blog-6570061087276796800.post-40127834533755386412014-08-29T16:46:51.755-04:002014-08-29T16:46:51.755-04:00They meant absolute?

I also found the first question hard to follow--again, for simple lack of perspicuity. If these sample questions exemplify what's on the new New York Common Core tests, this is a big problem.

Whether or not it's even possible to teach "dreaming", this is not something we should ask for.<br /><br />I have the same problem with "habits of mind".
