Representing quantity fractions A | NSW Curriculum Website

MA3-RQF-01 compares and orders fractions with denominators of 2, 3, 4, 5, 6, 8 and 10
MA3-RQF-02 determines $\frac{1}{2}$, $\frac{1}{4}$, $\frac{1}{5}$  and $\frac{1}{10}$ of measures and quantities

Prior Knowledge

• Partitioned Fractions (Stage 2)

Recognise the role of the number 1 as representing the whole

• Compare halves and quarters of different sized wholes
• Justify the need for fractions to refer to the number 1 as the common whole (Reasons about quantity)

Compare and order common unit fractions

• Compare unit fractions as numbers to the benchmark value $\frac{1}{2}$ 
• Compare and order unit fractions with denominators of 2, 3, 4, 5, 6, 8 and 10 by placing them on a number line

Solve problems involving addition and subtraction of fractions with the same denominator

• Represent the sum of fractions with the same denominator, recreating the whole, where the result may exceed one
• Find the difference between fractions with the same denominator and interpret the answer
• Solve word problems that involve fractions with the same denominator
• Use diagrams, objects and mental strategies to subtract a unit fraction from any whole number including 1 (the complement principle)
