Subordinating conjunctions worksheets

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

Subordinating conjunctions join a helper idea to a main idea and name the link: because (why), although (surprise), until (time), if (condition).

Five grades, four different sets of sentences: 5th and 6th grade share one. Print one here, or open a grade for examples and teaching notes.

Print by grade

  1. 3rd grade Core grade

    Examples and teaching notes

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

    Subordinating conjunctions (because, although, until, before, after, while, if) attach a helper idea to a main idea and label the connection: reason, surprise, time, or condition. Third graders choose the one whose label matches the logic of the sentence.

  2. 4th grade

    Examples and teaching notes

    Fourth graders work the fuller set (since, unless, though) and sharpen the contrasts: because versus although is the reason-versus-surprise fork, until versus while splits the timing. Reading the whole sentence before choosing is the skill.

  3. 5th grade

    Examples and teaching notes

    Fifth graders use the full family: although, because, unless, while, since, whenever, to build complex sentences where one idea leans on another. Choosing the right subordinator means reading the logic between the clauses: cause, contrast, condition, or time.

  4. 6th grade

    Examples and teaching notes

    Sixth graders pick subordinators in sentences where several are grammatical but only one matches the logic: although concedes, because explains, unless sets a condition. This is the sentence machinery of academic writing, tested one joint at a time.

  5. 7th grade

    Examples and teaching notes

    Seventh graders choose from a wider set of subordinating conjunctions: even if, as long as, provided that, so that, now that, once, whenever, wherever, as if and whereas join because, although and unless. The sentences are longer and the wrong choices are closer, so the student reads both clauses to the end and names the link before choosing.
