Coming Soon

Additive Reasoning

This InterventionPack domain is currently in development. It will focus on pupils’ understanding of addition as a structure, including combining, increasing, part-whole relationships, missing parts and efficient calculation strategies.

What this pack will focus on

  • Part-whole relationships
  • Combining and increasing structures
  • Missing-part reasoning
  • Efficient addition strategies
  • Misconceptions around addition as only “counting on”

What will be included

  • Diagnostic assessment
  • Individual pupil reports
  • Class summary dashboard
  • Whole-school overview
  • Targeted intervention resources
  • Printable worksheets and teacher notes

Why this domain matters

Addition is often treated as a simple procedure, but pupils need to understand the structures behind it. This pack will help teachers identify whether pupils understand combining, increasing and part-whole relationships, or whether they are relying on surface-level counting strategies.

This domain is not yet available

Additive Reasoning is planned as a future InterventionPack domain. For now, the live diagnostic and intervention resources are available through the Multiplicative Thinking pack.
