Stage 4

Fractions, decimals and percentages
Compare fractions using equivalence
  • Determine the highest common factor (HCF) of 2 whole numbers

  • Examine methods of generating equivalent fractions

  • Simplify fractions by using methods, including determining the HCF of the numerator and denominator or repeated simplification using common factors

  • Create fractions with the same denominator to compare their sizes

  • Compare and order fractions with different denominators

Round decimals to a specified degree of accuracy using approximations
  • Round decimals to a given number of decimal places

  • Apply the notation ≈ as a symbol of numerical approximation

  • Reason why an approximation may be more appropriate than an exact answer and vice versa

Identify terminating and recurring decimals
  • Use either dot or vinculum notation for recurring (repeating) decimals

  • Classify decimals as recurring or terminating

Identify and make use of the relationship between fractions, decimals and percentages to carry out simple conversions
  • Classify fractions and percentages as rational numbers

  • Recognise and explain that numbers with terminating or recurring decimals are rational

  • Represent fractions as decimals (terminating and recurring) and percentages

  • Represent terminating decimals as fractions and percentages

  • Represent improper fractions as mixed numbers and decimals, and vice versa

  • Represent percentages as fractions and decimals

Examine the concept of irrational numbers
  • Find approximations of irrational numbers using digital tools

  • Locate the approximate position of irrational numbers on a number line

Order and compare the value of fractions, decimals and percentages
  • Locate positive and negative fractions, decimals and mixed numbers on a number line to compare their relative values

  • Compare and order fractions, mixed numbers, decimals (terminating and recurring) and percentages

Solve problems that involve the addition and subtraction of fractions
  • Represent addition and subtraction of fractions with the same or unrelated denominators

  • Solve problems involving adding and subtracting fractions and mixed numbers, including finding a common denominator

  • Solve problems that involve subtracting a fraction from a whole number, with and without the use of digital tools

Solve problems that involve the multiplication and division of fractions and decimals
  • Compare and generalise the effect of multiplying or dividing by a number with magnitude between zero and one

  • Represent multiplication and division of decimals

  • Represent multiplication and division of fractions, including mixed numbers

  • Multiply and divide decimals, using digital tools to solve problems

  • Multiply and divide fractions and mixed numbers, with and without using digital tools to solve problems

  • Compare initial estimates with the results of calculations

  • Apply knowledge of fractions and decimals of quantities to solve problems

  • Apply knowledge of multiplication and division of fractions and decimals to solve problems

Represent one quantity as a fraction, decimal or percentage of another, with and without the use of digital tools
  • Represent one quantity as a fraction, decimal or percentage of another by considering appropriate units

  • Calculate percentage increases and decreases in various contexts

  • Examine the financial applications of percentage increase and decrease, including profit and/or loss as a percentage of cost price or selling price

Solve problems that involve the use of percentages
  • Apply knowledge of percentages to calculate quantities in various contexts

  • Apply knowledge of percentage increases and decreases to solve problems in various contexts

  • Solve real-life problems involving percentages using the unitary method or other techniques

  • Solve financial problems involving percentages, specifically considering GST, profit and loss
