  • Fluently add and subtract within 1,000
  • Multiply one-digit numbers by multiples of 10 (10–90)
  • Understand place value patterns: 10 × a one-digit number

Fractions

  • Understand unit fractions as equal parts of a whole
  • Place fractions on a number line
  • Recognise equivalent fractions using visual models
  • Compare fractions with the same numerator or denominator
  • Understand whole numbers as fractions (e.g., 3 = 3/1)

Measurement & Data
