About these conjunctions worksheets

A conjunction joins words, groups of words or whole sentences. The lesson sheet covers and, but and or, then so and because, then time words such as when, before and after.

Students circle conjunctions, choose the one that makes sense, fill in sentences from a word bank and join pairs of sentences. For joining two full sentences with a comma, see compound sentences.
