Read your sentence out loud-- only what you wrote. Is it a complete sentence? Or, is the other half in the next sentence? Does the sentence have a subject and verb (actor and action)? Stop after each period-- if you have to ask "What then?" or "So what?" or "because what" after a period, you might have a sentence fragment.
Example:
Fragment: First sentence - He was going because. (because what?)
Fragment: Second sentence: He bought tickets.
Full sentence put together: He was going because he bought tickets.

Say something says, "The angry dog." then if the next thing said "He continued barking until the morning." then you fix the fragment by saying "The dog barked."
