Introduction
Learn to name and write non-unit fractions, recognising them as multiples of unit fractions. Learn that fractions are numbers that can be positioned on a number line. Compare and order fractions with the same denominator or same numerator.
Teaching points
Non-unit fractions
- Teaching point 1: All non-unit fractions are made up of more than one of the same unit fraction.
- Teaching point 2: Non-unit fractions are written using the same convention as unit fractions. A non-unit fraction has a numerator greater than one.
- Teaching point 3: When the numerator and the denominator in a fraction are the same, the fraction is equivalent to one whole.
Fractions as numbers
- Teaching point 4: All unit and non-unit fractions are numbers that can be placed on a number line.
- Teaching point 5: Repeated addition of a unit fraction results in a non-unit fraction.
- Teaching point 6: When the numerator and the denominator are the same, the value of the fraction is one.
Comparing fractions
- Teaching point 7: Non-unit fractions with the same denominator can be compared. If the denominators are the same, then the greater the numerator, the greater the fraction.
- Teaching point 8: Non-unit fractions with the same numerator can be compared. If the numerators are the same, then the greater the denominator, the smaller the fraction.
