1) A group of boys is playing football.
or
2) A group of boys are playing football.
My teacher told me the first sentence is correct since of boys can be ignored to make:
A group is playing football.
It feels very awkward in my mouth to say boys is.

Yes, you should feel awkward using boys is. But you should not so using a group (of boys) is.
You feel awkward because you think 'is' is for 'boys'.
You should not feel awkward because 'is' is for 'group' there!
I did not think to provide an answer one more level deep. I thought the OP is from a non-native speaking country and this question is a very basic question with a straightforward answer 'a group is'. But since learned registered users here want this answer to be utterly foolproof, I'm adding this.
Okay,
'A group of boys are playing ...'
is possible!
Soon, as Christmas is nearing, you may observe that...
'A number of offers are getting displayed on the hoardings.'
[By 'offer', I mean festive season offers]
How?
Well, here, the noun 'offer' is used in its plural form i.e. 'offers'. And, when you quantify the plural noun with 'A number of', a plural verb ('are') is used which will look more natural.
Quantifying means using some words to show number of something - how much, how many etc. In above sentences, A group of, A number of etc. are used as quantifiers.
Another example can be built:
A lot of monkeys were on the tree
Do you get it?
I've closely observed the education systems in India, and I won't be surprised if 'a group of boys are...' will surprise almost every non-native teacher teaching English! I'm sure this is the same case with Nepal. Said that, if your teacher says that 'a group of boys is playing something'.... it's fine.
a group (of boys) is (I don't know why it was formatted as code), evading the issue of *a group of boys are*, which in my opinion is the crux of the question, it could be misleading.

The answer depends on what you want to further assert about that group.
A group of boys are playing football together. ["is" would be wrong or at least very weird here!]
A group of boys are/is playing football on the field. ["is" and "are" mean slightly different things.]
There is only one group of boys playing football on the field. ["are" would be wrong here!]
In general, a group can be viewed as a single unit or as its individuals. The context may allow only one viewpoint, as in the first and third example, or it may allow both viewpoints, as in the second example. Accordingly, you have to decline the verb based on which viewpoint you use. So even the second example must further split depending on the wider context.
Who are playing football on the field? A group of boys are playing on the field.
What is that group of boys doing on the field? That group of boys is playing on the field.
In these two examples above, people normally follow the original viewpoint of the question unless it is necessary to change it, so it would be very unusual to use the opposite number (singular/plural) for the verb, although I think it is still grammatical.
As an antidote do all the people saying 'group is singular, therefore you should use is', here's a Language Log post by Geoff Pullum arguing against plural agreement for quantificational uses of mass nouns.
As a L1 (British) English speaker, I would definite use are over is.
1 Your ear is right. Sometimes we make the verb agree with the closest noun, even if that noun is not the subject of the sentence. This is true especially with longer sentences, when the actual subject is far away from the verb.
As an example of this, in A Comprehensive Grammar to the English Language, the authors give several examples, including
The President, with his advisors, are preparing a statement on the crisis.
This may not be grammatically correct, but on the basis of proximity, it is something that many might say and believe correct, because it sounds better.
Your sentence sounds even worse to me (native speaker of American English) in the past tense:
a. A group of boys was playing in the yard. (sounds yucky)
b. A group of boys were playing in the yard.
(a) is okay, because was agrees with group (considered as a singular noun), and many teachers and speakers will prescribe that this is the only correct usage.
But to many native speakers
(b) is also okay, because of two reasons. First, boys is the nearest noun and, as you say, the sentence can sound off/wrong to some when they use a singular verb next to the plural boys.
And, second, there is a more technical answer:
2 With words such as group there is a special use:
Collecting noun phrases (a bunch of, a group of, a set of, etc.) take either a singular or plural verb, depending on whether the emphasis is on the individual units or on the group as whole:
A group of boys were digging in my flower beds!
A set of 12 dishes is all you need for the dinner party.
English is not my mother tongue. Dutch is. But according to my english teacher, one should look at the subject of the sentence.
A group of boys is/are playing football
Who is/are playing football?
A group of boys.
A group of boys is actually singular. We are talking about a single group here. So the verb used on this subject should be singular too.
This makes: a group of boys is playing football.
I understand that conventions on this are different in the UK than in the US. But speaking of REAL English, like we speak it here in America ... :-)
Your teacher is correct: "a group is". Yes, it may sound strange to you to say "boys is" together, but that's just a coincidence of the way the words in the sentence were ordered. The subject is not "boys", but "group".
Consider this sentence: "The man who owns three houses is tall." Would you think that you should use "are" instead of "is" because "houses" is plural? No, because the subject of the sentence is not "houses", but "man". The man is tall; it is not the houses that are tall.
Same thing here. Grammatically, it is not the "boys" who are playing football, but the "group". Yes, in real life the "group" and the "boys" are the same thing, but GRAMMATICALLY they are distinct.
