Teacher pack · Adding Fractions

Marking scheme

Band	Marks	Descriptor
Mastered	39–46	Applies adding fractions fluently, including in unfamiliar contexts, with clear justification.
Secure	30–38	Reliable in routine questions; reasoning is mostly complete.
Developing	18–29	Secure in scaffolded items, inconsistent once support is removed.
Emerging	0–17	Needs re-teaching of the core rule before progressing.

Teacher notes

Set the warm-up as a five-minute starter; it diagnoses readiness for adding fractions 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 Fractions.

Common student mistakes

Confusing adding fractions with a neighbouring idea in fractions.

Teaching tips

Model one worked example of adding fractions 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 adding fractions with justification-only questions.
Design your own adding fractions question and write the mark scheme for it.
Link adding fractions to the next subtopic in Fractions and explain the connection.
