I don’t know the ultimate origin of this worksheet, but it is great.

If he home schools…. what is his agenda with the criticism……so much of this is political.

This was featured on “The Blaze”. The actual parent was found and interviewed. http://www.theblaze.com/stories/2014/03/25/frustrated-father-who-obliterated-common-core-in-viral-post-shares-how-his-sons-teacher-reacted/ The dad’s name is Jeff Severt.

I would say the agenda is, common core makes absolutely no sense in the way it is being administered. It is not teaching our children how to think but rather a ‘system’ that will actually prevent them from using there brains to properly analyze anything. The IDEA behind common core is a sound one, the administration and the ivory towered ‘think tankers’ who have no association with actual education who set it up…? Don’t get me started. You are right Jo, so much of this IS political and not with good intentions. When math has gone from a 2 or 3 step process to a 42 step process, to quote the bard ‘something is rotten in the state of Denmark.” The political establishment has proven over and over they DO NOT want students to be able to think but rather go blithely along with any ‘authority figure’ that tells them anything. This gets us George Orwell’s scariest nightmare, not student’s who can think and act for themselves.

Engineer says

Common Core math is another example of how Academic PhD’s in the field of Education use Schools as laboratories to conduct experiments. I taught PLTW in a high school for a couple of years and when it came to ‘bright’ students doing ENGINEERING EQUATIONS the way they are done in the Real World and in College level Engineering courses, neither the Students nor the Math teachers could work the problems. This is why the United States is falling behind globally in Education/Science/Math. Progressive education is a Failure and the students are placed at risk from our own system. Parents need to stand up and question both Math Teachers and Academic Administrators. I have attempted to discuss such problems with ‘teachers’ and they circle up their wagons and defend themselves when outsiders with real world experience challenge them. Most curriculum are ‘canned’ processes that if you think outside the box, you become a trouble maker. Time to give teachers and educators an “F” for their efforts!

I’m also a practicing engineer and a part-time educator (at the university level).

The example above is floating around the internet as a supposed example of how “bad” this method is. In reality, the problem above is a simple number line. There’s nothing new here. It was used as the basis of explaining addition, subtraction, negative numbers and graphing when I was in elementary school in the early 70’s.

It’s so strange to read these posts about how important math education is from people who clearly don’t remember their own basic math.

Keniki says

The problem isn’t the number line. The student, to whom the worksheet is written, doesn’t DO the math. He just has to find Jack’s mistake in doing the problem and write him a letter. In the length of time it takes the student to write the letter, he could do 5-10 more math problems and actually LEARN the math.

pelecypod says

It’s a common and effective teaching technique to ask the student to explain the method. I see no problems with this, other than perhaps an impatient parent.

A. Deno Vir, MD PhD says

They are teaching kids to do math in their heads and it’s a good idea. Think about it, who uses pencil and paper anymore? 427-316. Okay. First take 300 away and you get 127. Then take 10 away and you get 117, then take 6 away and you get 111. Really folks, it’s simple.

David says

The worksheet above, whether it is or isn’t a good way of learning math, is not “Common Core.” The Common Core itself doesn’t say that math must be learned this way or that way. So the poster of this worksheet says “I don’t know the origins of the worksheet.” So how can it mean anything? Is teaching math this way dictated by the Common Core? No. Was this math worksheet used in a classroom that follows the Common Core? Maybe, but ow do we know if we don’t know where the worksheet comes from? Even if this worksheet was used in a Common Core context, critiquing the particular teaching methodology is not a critique of the Common Core. If this is a website about “Truth in Education” but it is passing on urban legend satire that isn’t even verified or actually a critique of what the headlines say its a critique of, then what is the truth of that?
