Coordinating conjunctions worksheets
Each print is a different sheet with its own answer key. You don't need to sign up.
A conjunction joins ideas: and adds, but shows a difference, or gives a choice, so shows what happens because of it.
Four grades, each its own sheet. Print one here, or open a grade for examples and teaching notes.

-
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 Core grade
Each print is a different sheet with its own answer key. You don't need to sign up.
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).
