Think again....that was the exact wording of the question.

According to the teacher the answer is:

2+8=10
5+5=10
12-2=10

and so on....

I was in the camp of ten, deca, diez, etc.....

So when my son asked for help on this one I told him to write names (as he thought he should do also). When I got the sheet back yesterday it had a big question mark and the "Correct" numerical examples.


It just kinda rubbed me wrong because this teacher tends to really come down on her students when they miss something.

That teacher is an idiot.
I had a similar dolt for 5th grade math.

We were doing decimal rounding, and I wanted to demonstrate that I understood the process.
So when he said: "Round .009345 to the nearest thousandth," I wrote .009000, for example.

He marked every single one wrong, AND gave me a "detention" so that he could give me extra help.

OK, now that I've got a college degree, I understand why .009000 is different from .009, but at that grade level, you are taught that trailing zeroes in decimals are meaningless.

I'm 34, an accountant, and still don't know what the difference is between .009000 and .009 :confused:

i can sort of understand why the teacher word it the way he/she did. when kids are that young, you have to be careful to pick the right wording. obviously he/she cannot use the word "equation" or something of that sort. so he/she probably figured "name" would replace it just nicely. but he/she should have given an example or explained it before assigning the hw.

That teacher is a nutjob.
His question should have been, 'write 3 things that are equal to ten'.
Send the teacher back to English 101!

Which is a good point - mathematically, the numbers are EXACTLY the same, and this WAS a mathematics class. I was just trying to give the dopey teacher the benefit of the doubt. :)

I may be a little off since it's been a good 5 years since my last chemistry class, but scientifically, trailing zeroes are considered significant figures and indicate the level of accuracy used in a measurement or calculation. If I say something is .009000 meters in length, that implies that I used a measuring tool that allowed me that level of accuracy (to one millionth of a meter). .009 says my measuring tool only gave me accuracy to one thousandth of a meter, and it truth it could be .0094 meters.

"Write 3 names for 10" was on my 1st graders math homework tonight, as you may be able to tell, i didn't know the answer to that question. Lucky for me you all figured it out.

Dumb question is dumb.

If you want 3 sums that =10 then ask "write 3 sums that =10".

Names!!! FFS

They should be teaching the proper mathematical terminology. Write three expressions that evaluate to 10.

Holy necro, but anyway...

I am not a math expert, but you cannot round .009345 to .009000
If you specify more digits after the .009 it's obviously not rounded as was requested in the test.
