[quote=Anonymous][quote=Anonymous][quote=Anonymous][quote=Anonymous]Wow - if that problem on the top of the paper is comon core - we are all in trouble - what the hell is that?[/quote]

What it is, is NOT a  Common Core math problem.

The Common Core is standards. It's not a curriculum. It's not worksheets. It's standards. At the end of third grade, students should be able to [whatever]. That's it.

If somebody wrote a worksheet, that doesn't make it a Common Core worksheet.

(Also, the guy with the B.S. in EE should be embarrassed. This is not a difficult problem.

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,

Student)[/quote]

TO be fair, the worksheet that that teacher designed also included incorrect subtraction of the 10s.   The smaller jumps (that are supposed to represent taking away 10s) start at 127 and the student "Jack" was supposed to take away 10 each time... but his first jump, he took away 20 for some inexplicable reason, so he labeled the first jump back 107 (instead of 117).   I think that fact is (a) too confusing for a 3rd grader to deal with on this type of worksheet and (b) is part of what totally confused parents on this worksheet.

At any rate -- this worksheet ISN'T a "Common Core" worksheet.   Common Core doesn't have a way you have to teach math.  It just says kids need to be able to add, subtract, have fluency in calculations etc. but a certain grade.[/quote]

Actually I don't think that was on the original worksheet.  That was the "highly educated in higher math" parent's flailing attempts to solve it.  The numbers on the worksheet clearly  show that the person doing the original work subtracted three 100s and then 6 ones, skipping the 10s. I.e. 427 - 327 - 227 - 127 - 121. The parent is an idiot.[/quote]
