Semantic relationships

Misconceptions
Stored on the entity so worksheets, quizzes and lesson plans all target the same known errors.
Learners over-generalise a special case of sets to every situation.
Correction — Present a deliberate non-example and ask why the rule fails.
Students treat sets as a rule to memorise rather than a relationship to understand.
Correction — Anchor the rule in a visual model first, then abstract it — the model is the explanation.
Curriculum alignment
Curricula, boards and countries are data — adding one never changes the architecture.

Standard curriculum demand, unscaffolded.
Multi-step questions and unfamiliar contexts.
Stretch tasks that need reasoning, not recall.
Competition-style problems built on the same idea.
Board-styled questions with mark schemes.
Learning intent
Not every visitor wants the same thing. Each intent routes to the resource that actually does that job.
Audience views
Sets in Grade 2, surfaced differently for each reader.

Frequently asked
- What sits underneath Sets in the knowledge graph?
- 0 domains, 0 strands, 0 units, 3 chapters, 12 topics, 60 subtopics, 360 concepts and 1,800 micro-concepts — every one of them carrying its own worksheets, quizzes, flashcards, lesson plans and AI tutoring.
- What should a learner already know before Sets?
- The graph lists Dictionaries, Tuples, Functions as prerequisites. Each links to its own practice so a gap can be closed before moving on.
- Which grades is Sets taught in?
- Typically Grade 2, Grade 3, Grade 4, though every resource can be regenerated for any grade in the platform.
