Unlocks

Finding halves and quarters (age 5+)ages 5–6Understanding quarters extends from understanding halves — both are equal parts but quarters requires dividing into 4

Fractions of amountsages 6–7Working with fractions extends from Y1 understanding of halves

Halves & Quarters of Shapesages 6–7Partitioning shapes into halves extends from Y1 understanding of halves

Telling Time: Hours and Half Hoursages 5–6Understanding 'half past' benefits from the concept of halves
