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
A colon can follow a complete clause to introduce a list or explanation. In these conventional constructions it should not interrupt a verb-object or preposition-object relationship.
Test whether the words before the colon can stand as a complete clause. Then identify what follows.
Original worked input: Original excerpt C: We need three items: paper, pens and tape. The task is to check a colon’s introduction. The answer is “complete clause introducing a list”. Evidence: We need three items: paper, pens and tape. Reasoning: complete clause introducing a list is supported because a complete clause precedes and introduces the list. We need: paper is not the same construction.
- Read the supplied worked case and identify the part named in this lesson. An adult can model unfamiliar words.
- Test whether the words before the colon can stand as a complete clause. Then identify what follows.
- Check the worked solution: complete clause introducing a list. Evidence: We need three items: paper, pens and tape. Reasoning: complete clause introducing a list is supported because a complete clause precedes and introduces the list. We need: paper is not the same construction.
- Use the new primary and practice cases. Give a reason from the actual words before checking the feedback.

complete clause introducing an explanation
Evidence: Jo waited for one reason: the room was locked. Reasoning: complete clause introducing an explanation is supported because a complete clause precedes and introduces the reason. We need: paper is not the same construction.
Take it further
Changed-input task: Original excerpt C: Jo recorded: the date and count; the colon splits recorded from its object. Give an evidence-based answer before looking at the model. Expected reasoning: Evidence: Jo recorded: the date and count; the colon splits recorded from its object. Reasoning: incorrect colon splitting a verb from its object is supported because the colon wrongly separates need or recorded from its direct object. We need: paper is not the same construction. Then write a brief alternative sentence, paragraph, source note or scene that demonstrates the same operation; label new fictional details and preserve source limits.
