Needs first
- Scale and similar shapesREQUIRED
Scale diagrams and maps extend KS2 scale-factor work with similar shapes
- Proportional Reasoning VocabularyREQUIRED
Scale diagrams and maps require 'scale factor' as a precisely defined term
- Proportion Graphs
Scale diagrams use proportional relationships that can be represented on double number lines
- Unit Conversions
Map scale problems often require converting units (e.g. cm to km)
