Scale question

[RiskyP]

I saw someone was talking about practicing scales in thrids and sixths... I was wondering what that means exactly and how would you go about doing that?

[Hmoll]

Using C major scale in thirds as an example it could mean two things:
1) Left hand beginning on C and right hand beginning on E (the third degree of the scale).
2) Practising both hands in double thirds.

Would you then play the C major scale starting on E, or the C major scale in the right hand and the E major scale in the left... hehe, it actually sounds somewhat fun.

The former.

Playing C major with one hand and E major with the other is fun alright, but it not a very useful excersice unless you plan to play modern music...
