Introduction
Learn to name and write unit fractions. Recognise and show unit fractions of areas, lengths and quantities. Relate numerators and denominators to parts and wholes; explore how the greater the denominators, the smaller the unit fraction.
Teaching points
- Teaching point 1: A whole can be divided into any number of equal parts.
- Teaching point 2: Fraction notation can be used to describe an equal part of the whole. One equal part of a whole is called a unit fraction. Each unit fraction has a name.
- Teaching point 3: Fractional notation can be applied to represent one part of a whole in different contexts.
- Teaching point 4: Equal parts do not need to look the same.
- Teaching point 5: Unit fractions can be compared and ordered by looking at the denominator. The greater the denominator, the smaller the fraction.
- Teaching point 6: If the size of a unit fraction is known, the size of the whole can be worked out by repeated addition of that unit fraction.
