Supplied materials

  • Paper and pencil, or a browser text area. All named people/events/records are fictional learning inputs.
  • Worked case: Excerpt A: We practice reading, listening and speaking. Excerpt B: The model is ready; the labels need checking. Excerpt C: We need three items: paper, pens and tape. Excerpt D: The model, a paper prototype, is ready; analyze a paper prototype.
  • Primary check: Excerpt A: We plan to read, to listen and to speak. Excerpt B: The model is ready, and the labels need checking. Excerpt C: Jo waited for one reason: the room was locked. Excerpt D: The model with the torn hinge is here; analyze with the torn hinge.

Learn the idea

Related independent clauses can join with a semicolon or comma plus a coordinating conjunction. An introductory dependent clause takes a comma before the main clause; separate statements can use periods.

Count clauses and inspect the connector the task explicitly supplies. Apply the matching punctuation form.

Original worked input: Original excerpt B: The model is ready; the labels need checking. The task is to choose a clause join. The answer is “semicolon between related independent clauses”. Evidence: The model is ready; the labels need checking. Reasoning: semicolon between related independent clauses is supported because each side of the semicolon is a complete related clause. A semicolon is not used simply for a long pause.

  1. Read the supplied worked case and identify the part named in this lesson. An adult can model unfamiliar words.
  2. Count clauses and inspect the connector the task explicitly supplies. Apply the matching punctuation form.
  3. Check the worked solution: semicolon between related independent clauses. Evidence: The model is ready; the labels need checking. Reasoning: semicolon between related independent clauses is supported because each side of the semicolon is a complete related clause. A semicolon is not used simply for a long pause.
  4. Use the new primary and practice cases. Give a reason from the actual words before checking the feedback.

Helpful tips
  • A comma alone does not join two independent clauses.
  • A semicolon is not used simply for a long pause.
Original excerpt B: The model is ready, and the labels need checking. Use excerpt B only. Which punctuation join fits the stated construction?

comma with coordinating conjunction

Evidence: The model is ready, and the labels need checking. Reasoning: comma with coordinating conjunction is supported because the comma accompanies and or but between complete clauses. A semicolon is not used simply for a long pause.

Take it further

Changed-input task: Original excerpt B: Although the hinge held, Jo recorded its limit. Give an evidence-based answer before looking at the model. Expected reasoning: Evidence: Although the hinge held, Jo recorded its limit. Reasoning: comma after introductory dependent clause is supported because the opening dependent clause is followed by a comma before the main clause. A semicolon is not used simply for a long pause. Then write a brief alternative sentence, paragraph, source note or scene that demonstrates the same operation; label new fictional details and preserve source limits.
