Coordinating conjunctions across the grades
1st grade
And, but, and or are joining words: they connect two ideas into one sentence. First graders pick the joiner that fits, learning that and adds, but flips, and or offers a choice.
2nd grade
Coordinating conjunctions are the small joining words: and adds ideas together, but points out a difference, or offers a choice. Second graders pick the joiner that fits the meaning of the sentence.
3rd grade
The coordinating conjunctions (and, but, or, so) each signal a relationship: addition, contrast, choice, or result. Third graders choose the one that fits and start using them to build compound sentences.
4th grade
Fourth graders work with the full everyday set, including yet (a sharper cousin of but), and read more carefully to tell "so" (result) from "but" (contrast).
