Itunes 11 and syncing music problem?

How do i sync only my checked songs from my itunes 11 library onto my iphone 5?

At the top right of the iTunes box is a button for "devices". Your iPhone will show up there. Click on the button, then your phone.
The summary page shows up.
At the bottom check the box that says, "sync only checked songs…"
Apply.
Done.
