### Three IS Greater Than Two?

Subject: Greater than less than

My daughter is in 7th grade and got a few answers wrong on a test.
This was the question, "Write the words for the symbols."

> (with a line underneath)          greater than or equal to

Her answer was marked incorrect because she did not include the
word "is" greater than or equal to. Every answer was marked incorrect
because she didn't use "is." I am trying to find out if this is
correct.

Hi, Karen.

On one hand, this seems pretty picky. You'll certainly see plenty of
lists that briefly define these symbols as "greater than or equal to"
and similar phrases, without the "is"; that's all you need to show
that you understand the meaning of the symbol.

But if the teacher had previously made it clear that only the full
version, including "is," would be accepted on a test, then it is
reasonable to mark anything else wrong. Technically,  >=  (as we
write it in text) is not a conjunction or a preposition, but a verb,
and the "is" is essential in how we use it. For example,

3 > 2

means the sentence "3 IS GREATER THAN 2," not just the phrase "3
GREATER THAN 2." And for many kids, that makes a huge difference. If
you were translating a sentence into algebraic terms, the latter
phrase would be "2 + 3" (that is, 3 more than 2). So I can support a
teacher emphasizing the precise meaning of the symbols, and asking
students to give only that as an answer. I would only object if no
they only had to say enough to show that they knew the general
meaning of the symbols.

If you have any further questions, feel free to write back.
