Help with musical intervals??

Question:I'm very bad at this stuff....pleazz give me the answers for this. I'm confused, i tried learning this stuff. I play the violin. Do u just count the spaces and lines between two notes to create intervals? For D major I got, of course, three open Ds, and under one of them it says 5, the other one 8, and the other one 6. I'm supposed to create the intervals? Do I just count up, counting the D as one, and then count up to 5 to get the interval for the D with the 5 under it??!
And I have to do teh same for the G major with three Gs, with 2, 7, and 3...
and for C major, with 3 Cs with 1, 4, and 5 under them.
HELP
thank you soo much

A D note with a 5 would mean start on D and count up 5 notes, counting the D as one. So: D E F# G A = a 5th up from D is A.

A D note with an 8 would mean start on D, count up 8 notes (which is the interval of an octave) : D E F# G A B C# D = or IOW, an octave up from D is D

Likewise, a D note with a 6 would be: D E F# G A B. or IOW, a 6th up from D is B.

For the G's -

A G with a 2 would be G A or IOW, a 2nd up from G is A.
A G with a 7 would be G A B C D E F#, or IOW, a 7th up from G is F#.
A G with a 3 would be G A B or IOW, a 3rd up from G is B.

Hopefully you can figure out the C's.

Rachel gave an excellent answer and I am by no means trying to steal her thunder, but sometimes learning song fragments helps with learning intervals.

If you learn tiny bits of the songs that contain the intervals you want to learn, it helps to you to internalize them much faster. For a minor second, think of Jaws. For a Major second, think of Do - Re - Mi from the Sound of Music. for a minor third, think of the middle of Somewhere Over The Rainbow (Someday I'll Wish Upon a Star) for a Major Third, Do - Re - Mi works again. For a perfect Fourth, think of Here Comes The Bride. For a Tri-tone (Augmented fourth or Diminished Fifth) think of "The Simp-Sons!" For a Perfect Fifth, think of the drone a bagpipe makes or "Oh When The Saints" Go Marching in! For a Minor Sixth, think of the Theme from Love Story (Where Do I begin, To Tell the Story of how great a Love Has been) For a Major Sixth use "Hi Lilly, Hi Lilly, Hi Lo." For a Dominant Seventh or Minor Seventh, think of the love theme from West Side Story, Somewhere. (There's a Place For Us) and for a Major Seventh, think of Bali Hi, from South Pacific. If you don't know any of these songs, ask your parents or teacher. I'm sure they will be able to help.

Step two, learn the notes that these songs are played on in the keys that you want to find the intervals. It's a little time consuming, but much easier than it sounds. Hope this helps.
