AC9M5N04 Year 5 Mathematics

This Content Descriptor from Year 5 Mathematics provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

recognise that 100% represents the complete whole and use percentages to describe, represent and compare relative size; connect familiar percentages to their decimal and fraction equivalents

Elaborations

• 1 recognising applications of percentages used in everyday contexts; for example, the bar model used for charging devices indicating the percentage of power remaining; advertising in retail contexts relating to discounts or sales
• 2 creating a model by subdividing a whole; for example, using \(10\) x \(10\) grids to represent various percentage amounts and recognising complementary percentages, such as \(30\)% and \(70\)% combine to make \(100\)%
• 3 creating a model by subdividing a collection of materials, such as blocks or money, to connect decimals and percentage equivalents of tenths and commonly used fractions \(\frac12\), \(\frac14\) and \(\frac34\); for example, one-tenth or \(0.1\) represents \(10\)% and one half or \(0.5\) represents \(50\)%; recognising that \(60\)% is \(10\)% more than \(50\)%
• 4 using physical and virtual materials to represent the relationship between decimal notation and percentages; for example, \(0.3\) is \(3\) out of every \(10\), which is \(30\) out of every \(100\), which is \(30\)%)
