Conjunctions, or “joining words,” connect words or groups of words in a sentence.

Many conjunctions are high-frequency words, such as and, commonly understood and used by children in kindergarten and first grade. Spelling practice for conjunctions can continue through Grade 2, but conjunctions are not taught as grammar until third grade.

Teaching Conjunctions

In Grade 3, students learn the three most common conjunctions (and, or, but) are coordinating conjunctions, which combine related sentences into a compound sentence (the water was warm, but I didn’t go swimming). They learn when to use each of these three common conjunctions: to add information (and), to show a choice (or), and to show a difference (but).

Students begin to learn some common subordinating conjunctions (although, because, if, when, before, after, while, whether, since, until) they can use to make complex sentences (I went swimming although the water was freezing). Students learn that there are many more subordinating conjunctions than coordinating conjunctions, and word study for conjunctions should continue to introduce more subordinating conjunctions and provide opportunities for students to use and identify correlative conjunctions.
