Describe the number 534 in the following ways:
How many 100s=
How many 10s =
How many 1s =

Now the correct answers, as certified by 2 degreed engineers with many hours of higher level math (me and my wife) and a certain 4th grade student, are 5, 53, and 534.
According the some common core worksheet writer, the answers are 5, 3, and 4.

If the question asked "how many in the 10s place", etc., common core answers would be correct. But they didn't, and 5, 53, 534 are marked wrong, so now it's time to talk with the teacher o_O
 
I'm even more concerned that those are the same common core questions they are giving my 2nd and 3rd graders. I wonder when they move on to something new.
 
Maybe interpretation of the question?

I interpreted and answered how you describe the correct answer of 5, 3, and 4. However, I was assuming they were asking as such because of the common core curriculum.

But, if you answer as you did, wouldn't the correct answer be 5.34, 53.4, and 534, respectively?

If you are wanting to be engineer accurate...
There are 5.34 100s, 53.4 10s, and 534 1s.
I interpreted it as how many of each and would have answered 5, 3, 4.
 
The correct answer is;

5 rabbits with 3 pancakes on their heads spread out amongst 4 roofs..

I fucking hate common core.

I thought about it like with money. No idea what common core teaches but I would have gotten that one wrong.

Teaches the kids to do 5 extra steps to create a state of confusion..... Kind of like the rest of our gubberment.
 
Math lessons dont work in a vacuum.
I would be looking a few pages back in the lesson to see the lesson you are trying to teach.

Basically Matt typed my exact first thoughts.

Add 1 more engineer to the picnic...

Btw between all the engineers in this thread how many PEs...otherwise legally in NC you cant call yourself an engineer. I'm in SC so it is all good.:flipoff2:

I'm with you, boss. You can add some decimal places of you want to get picky.

Good mechanical engineers don't need a PE:flipoff2:
 
While I understand where you are coming from and that common core math might not be the best. It's in you and your kids best interest for you to learn the common core math and help them with how to answer the questions that the homework/test are asking. Sure you can teach them what you know and openly disrespect the test and the process but that isn't going to move your kid forward.

The way that you were taught math is not the way that common core is being taught. If you are smart enough to be an engineer and get advanced degrees then your smart enough to learn the common core and help your kid(s). Is it the best way to teach math? Maybe/Maybe not. But, it is the way it's being taught now. Remember, all the homework, classwork, and tests are all going to ask for the information in the same manner. The chance your kid see that question or a similar question on an EOG/EOC are pretty good. They will have your answers and the common core answers as choices. Only one will be right.

Agreeing or disagreeing with the common core doesn't have anything to do with the teacher or principal. It was a legislative decision.
 
And, I will add the most important thing that any parent can do for their kid is practice the multiplication/division tables. Know them front to back from 1-12 will make math much simpler for years to come. They don't really stress this much in school right now.
I really can't stress this enough.

Depends on the field. I'm not a CE and don't deal with the general public, and am not responsible for signing off on things that require PE licensure. No one gives a shit about PE licenses in most areas of industry because there is no need for it. Being a PE is only important for certain things that I have no interest I doing. My late father was a PE, but we did very different things.


Yes, I'm a giant nerd too.

i got 5,4, and 3.

they arent teaching math. they are teaching how to do math. its an excercise in recognition of placemarkers.

they were looking for how many times the placemarker for the 100s place had been tripped and so forth.

like on a speedometer, it had been rolled 5 times in the 100s slot
3 times in the 10s slot
4 times in the 1s slot

its laying the foundation for the language of math.

Believe me I get it and am in the same boat, in fact we used to work for the same company just in very different departments and locations, however NC has a law as part of their employment/restricted class/exempt list that in the state of NC your job title cant be "engineer" unless you are a PE.

That is all I was getting at just a funny dig.
 
My boy does not start K for another year, so I haven't been exposed to the common core crap yet.

I read the question and maybe due to the way it was presented thought the answer was 5, 3 and 4. Maybe that is because I am always thinking of money and that would be the most logical way to pay for something in cash that cost $534.

For the record, I am an engineer too. ME actually. I do not have my PE license either. I work for a global company and the VAST majority of engineers here do not have there PE. The company does not require it, but we all have the word 'engineer' in our title.
 
I'm with "BigBody79" & "drkelly"! Even before I got to their reply, I was thinking, "Hold on Engineers; This is 4th. Grade, Not NASA"! I Was, a whiz, in math! [5/3/4] But Never understood Algebra! I Barely passed the class, using plain old math.
 
You damn engineers. You're overthinking it and missing the base (ahem, core) logic for what it is. It's about how the "base 10" number system works.
Numbers are just an arbitrarily defined system for quantifying groups of things, digits are representations of the number of groups once you hit the top of your system.
10 is the most common grouping (probably b/c of what's on your hands).

The key here is it does NOT say "describe using 3 DIFFERENT ways".
Thus the assumption is a combination of them (which is what we naturally do w/ numbers), what digit combination together makes 534..
It's 5 100s, AND 3 10s AND 4 1s.

You boneheads that said 5.43, 54.3 and 543 would have the number 592.47.

Rephrase it into binary or hexadecimal and you'll see the logic holds the same.
Pffft, engineers. Bah.

Typical...
Start off with 534, and then somehow turn it into 543 :flipoff2:
