Fractions, Decimals & Percentages
Look for and use mathematical structure: exploit the relationship between fractions, decimals, and percentages; use factor pairs to simplify multiplication; apply angle facts to find unknowns; use properties of regular polygons systematically
Typical age: 9–10 years
“When your child notices that fractions, decimals, and percentages are just different ways of writing the same thing, do they use that understanding to switch between them fluidly when it makes a calculation easier?”

- Factors, multiples, and primes
Factor pairs as structural tool for simplifying multiplication
- Using Mathematical StructureREQUIRED
Age 8-9 using structure is prerequisite to age 9-10 level
- Angle Sum Rules
Angle facts (360°, 180°) are structural tools for finding unknowns
- Spotting Patterns
Exploiting relationships between fractions, decimals and percentages requires pattern recognition across representations
