Free 3rd Grade Conjunctions: and, but, so, because Worksheet

Students learn that conjunctions are joining words that link two ideas into one sentence, and that each one shows a different relationship: adding, contrasting, giving a result, or giving a reason. They choose the best conjunction, join pairs of sentences, find conjunctions in longer sentences, and write their own. Using conjunctions well moves writing on from short, choppy sentences.
