Applying number
Students calculate proportions, key percentages and simple rates involving money, time and measurements. For example, students can generally:
solve a word problem involving fractions
solve routine problems involving simple ratios.
Students can form estimates and approximations. For example, students can generally:
form estimates and approximations of rational and irrational numbers and simple expressions
interpret and justify the reasons for making estimates and approximations.

Calculating
Students calculate with four operations using integers, key percentages, decimals and common fractions. For example, students can generally:
solve a problem involving addition and subtraction of decimal numbers with different number of decimal places
use simple ratios in familiar practical situations
identify solutions of multi-step word problems involving common fractions or key percentages.

Rational and irrational numbers
Students identify and represent rational and some irrational numbers and compare and order them in respect to their properties. For example, students can generally:
identify a rational expression with the same value as a given fraction
identify range within which the square root of a three-digit number lies
identify the rational number that is a solution to a routine word problem, with access to a calculator
compare and order rational and irrational numbers, with access to a calculator.

Overall Aim:
In number, students at the minimum standard at Year 9 identify, compare and order integers, decimals, key percentages and common fractions. They can identify equivalent representations of common fractions, key percentages and decimals.
Students, meeting the minimum standard, can apply common strategies to calculate simple proportions, percentages and simple rates used in familiar practical situations. They can use common methods to form estimates and approximations of rational and irrational numbers and simple expressions.
