The concept of the question doesn't bother me. It's trying to get the kid to understand that subtracting 316 is the same as subtracting 300, then 10 and then 6. It's trying to teach number sense. Kids can learn to grind through algorithms w/o really understanding what they're doing. This problem clearly shows that the kid forgot to subtract at the 10s place. Doesn't surprise me that an engineer is complaining; all they want is their formulas to crunch.
yes - agree 100%
How many of us simply learned "how to" without understanding the process behind it?
It's really pathetic to read about "educated" parents with no number sense.
And yes, they are STANDARDS. The standards are then turned into instructional frameworks. The frameworks are umbrellas for the curriculum guides, which vary from state to state and from county to county.
20:09, you're an idiot.

But logically, if the school doesn't teach something that's in the common core, then the curriculum must change, or the children will fail the standardized tests.
Drove me crazy when the principle told me that the curriculum wasn't changing.
I' m not pro or anti common core, I think schools should always be changing or moderating. But don't tell me things that just aren't true. Why are you hiding the truth?
Like I could keep my doctor...

He doesn't understand the math, we don't understand the math, and it's geared for a highly verbal child, and our son has a language disability.
There's also no proof that making math ridiculously hard in K through 3 will lead to better math students in the future. As in NONE. Or that forcing kids to read on grade level - when their actual level is several grades lower -- will help them understand and read better.

I agree that doing subtraction of 3-digit numbers on a number line is silly. But the worksheet isn't asking you to do that. The worksheet is asking you to see what is wrong about the subtraction problem on the number line on the worksheet -- basically, to explain that when you're subtracting a 3-digit number, you're subtracting hundreds + tens + ones.
(I also agree that it would be helpful to see the original worksheet, before the electrical engineer who doesn't understand number lines or place value wrote on it.)
Maybe this kind of number lines should not at all exist for 3 digit computations. Personally, I think that this is the key point.

What does concern me is that the Tea Party fringe seems to be using the education of our children now as a pawn in their desperate bid for relevance. After realizing they'd lost the fight on the Affordable Care Act, some of the Tea Party leadership began fixating on Common Core, believing it has something to do with Obama (it does not). CC is actually a genuinely grassroots and nonpartisan effort involving governors of both parties in multiple states.
I'm more embarrassed by my liberal friends who have jumped on the bandwagon, ironically without giving it very much critical thought. They're fixating on the wrong things like this idiotic woman who sent that letter to "Jack" and the equally stupid woman who testified, tearfully, before the Arkansas Board of Education, and are, frankly, just scared because kids aren't being taught things the same way they were. Admittedly, this makes it a little harder to help with homework, but it doesn't make the pedagogy unsound.
I'm so over the rose-colored images of our childhoods in the 70s and 80s. Supposedly we had better educations, all played in the streets unsupervised. What next: Better drugs? Things were not better then. They were just different. People really need to stop being so afraid of things they do not understand like Common Core, and be willing to know what they don't know.

Dear Jack,
What you did right was subtract the hundreds on the number line. What you did wrong was subtract seven tens instead of one ten and six ones. To fix your mistake, you should subtract one ten and six ones.
Sincerely,

I agree that is what "Jack" was supposed to do. I saw this worksheet on Facebook last week and figured it out.
However, the number line doesn't seem to match the the one 10 and 6 ones approach after the mark for 127. There are only 6 "tick marks" total (I assume they're supposed to represent 117, 116, 115, 114, 113, 112). So why does it stop at 112? Yet the last mark is labeled 121 - not the correct answer either. I am clueless on what that means. It looks like the student subtracted 20 and then five 10s.
It'd be nice to see an original version of this problem and not whatever the father might have filled in.

See 22:39. W/o the scribbling from the parent it appears its just a case of forgetting to subtract the 10s.
