JUDGING STANDARDS IN YEAR 4 MATHEMATICS

Reporting against the Achievement Standard

These assessment pointers are for judging standards of student performance in Year 4 Mathematics.

They are examples of what students may demonstrate rather than being a checklist of everything

they should do. For reporting, they are used to make on-balance judgements about achievement, based on what has been taught and assessed during the reporting period. They can also be used to guide the pitch of assessment tasks, develop marking keys and inform assessment feedback.

YEAR 4 MATHEMATICS ACHIEVEMENT STANDARD

By the end of Year 4, students choose appropriate strategies for calculations involving multiplication and division. They recognise common equivalent fractions in familiar contexts and make connections between fraction and decimal notations up to two decimal places. Students solve simple purchasing problems. They identify unknown quantities in number sentences. They describe number patterns resulting from multiplication. Students compare areas of regular and irregular shapes using informal units.

They solve problems involving time duration. They interpret information contained in maps. Students identify dependent and independent events. They describe different methods for data collection and representation, and evaluate their effectiveness.

Students use the properties of odd and even numbers. They recall multiplication facts to 10 x 10 and related division facts. Students locate familiar fractions on a number line.

They continue number sequences involving multiples of single-digit numbers. Students use scaled instruments to measure temperatures, lengths, shapes and objects. They convert between units of time. Students create symmetrical shapes and patterns. They classify angles in relation to a right angle. Students list the probabilities of everyday events. They construct data displays from given or collected data.
