So what was the actual complete text of the problem? Fins will have to provide you with the exact text as my daughter returned her folder binder to school Monday morning. I've looked online for the exact problem but couldn't find it. Here is the closest example: [Link: swvgs.us]

I know how to round off. But what I'm undecided on is if they would expect a 3rd grader to think advanced enough to consider 0 a hundreds place. You do algebra in Kindergarten. 2+_=4, 3-_ = 1, 9+_=10. That's all the simplest algebra ever, but we don't teach it as algebra.

Round the following numbers to the nearest hundred:
14 Then you posted: On February 17, 2014 at 20:52, Fins said...
There were two numbers to the problem. The first was 346. She rounded that to 300. Then the other one is 14. So how would you round it to the nearest 100? The first post implies there are more than one number. The second post says there were two numbers and says what she did. You do not quote the problem as stated.

Ernie, the question was
Round the following numbers to the nearest hundred:
346 _____ 14 ______
The debate is over 14. If you need more information to comprehend this question, I'll see if I can have the special ed teacher contact you.

That test for seniors? Serious?
Badly flawed questions - too many assumptions being made.

The leading zeroes concept might be WAY too much detail for a nine-year old to realize. It might, however, be part of the lesson or a previous lesson. You need to ask about that.
Did your kid ever learn that 1 = 01 = 001? And actually absorb it? Like I say, it's a tough concept. They learned it here at that age... On February 18, 2014 at 21:56, Fins said...
No kindergarten is doing that kind of math. 2nd and third grade are, but not kindergarten. I was teaching my kids algebra well before kindergarten. If you give me one shell, I'll give you 2 peanuts. How many peanuts will I give you if you give me two shells? CJ

The debate is over 14. If you need more information to comprehend this question, I'll see if I can have the special ed teacher contact you. Getting math right requires being very specific about how it's written. It did not take a special ed teacher to tell me that the problem you posed, Round the following numbers to the nearest hundred:
14 could not possibly have been the problem. You didn't notice that you wrote number s and then supplied only one number? How the hell does one answer an obviously impossible question? Then you wrote There were two numbers to the problem. The first was 346. She rounded that to 300. Then the other one is 14. So how would you round it to the nearest 100? But this is freakin' MATH and exactly how it's written matters a lot. You chide me for not getting it, but what you wrote was unclear enough that Mario claimed it was not about rounding off but about estimating. And he's pretty sharp. Hell, a good math teacher would have written the problem (it's not a question, it's a problem) as Round the following numbers to the nearest hundred:
346 _____
14 ______ or even better Round the following numbers to the nearest hundred:
1. 346 _____
2. 14 ______ We deal here every day with people who have trouble solving problems with A/V gear, such as the recent request for a device to convert optical to CAT5. Well, you can't. Light does not convert to electricity and plastic does not convert to copper. The actual problem is "What device can convert an optical digital signal to a balanced wired digital signal?" Stating it clearly and completely points to the answer, which is to look into how the signals are sent, and convert their transmission method from one style to another. You kid's math teacher is either mean or is too ignorant to realize that the problem as posed has too few parts to help point toward the answer. The teacher should have given another one or two examples to get the mind into the groove of rounding off before tossing in the grenade. That teacher did not use the problem to teach, but to eliminate!
