1. Counting and place value

Build secure Key Stage 1 understanding of counting and place value in Mathematics.

A common misconception is treating counting and place value in Mathematics as a memorised label instead of a usable idea with evidence.

Validation: Generated starter-map content for MVP breadth. It is structurally complete but still requires subject-expert review before production claims.

Starter concept map Pending expert review Prerequisite: Core vocabulary for counting and place value Extension: Extend toward number bonds and facts once counting and place value is transferable.

Stage progression

Repair foundation: EYFS Mathematics - Repair foundations in EYFS Mathematics if counting and place value is blocked by earlier knowledge.

Later outcome: Key Stage 2 Mathematics - Stretch counting and place value toward Key Stage 2 Mathematics once evidence is transferable.

Representative problem: Complete one short Mathematics task using counting and place value and explain one step.

Mastery signal: Explains counting and place value in their own words
