Marking scheme

Band	Marks	Descriptor
Mastered	31–37	Applies introduction to networks fluently, including in unfamiliar contexts, with clear justification.
Secure	24–30	Reliable in routine questions; reasoning is mostly complete.
Developing	15–23	Secure in scaffolded items, inconsistent once support is removed.
Emerging	0–14	Needs re-teaching of the core rule before progressing.

Teacher notes

Set the warm-up as a five-minute starter; it diagnoses readiness for introduction to networks before you teach.
Guided practice is the pivot point — circulate here rather than during independent practice.
Mark the reasoning questions with the marking scheme bands, not raw totals, so progress is comparable across variants.
Students who band Emerging should repeat the Easy variant of this same subtopic before moving on within Networks.

Common student mistakes

Confusing introduction to networks with a neighbouring idea in networks.

Teaching tips

Model one worked example of introduction to networks under a visualiser before handing the sheet out.
Ask students to predict which question they will find hardest, then check the prediction afterwards.
Pair Developing students with Secure students for the guided practice block only.
Use the answer key as a self-marking station rather than collecting the sheets in.

Extension activities

Challenge worksheet on introduction to networks with justification-only questions.
Design your own introduction to networks question and write the mark scheme for it.
Link introduction to networks to the next subtopic in Networks and explain the connection.
Ten-minute timed practice to convert accuracy into fluency.

Question progression

Recognition → understanding → application → reasoning → mastery. The ladder adapts to Grade 12, and every rung stays on introduction to networks only.
