Number: Addition and SubtractionBy the end of Year 3, students recognise the connection between addition and subtraction and solve
problems using efficient strategies for multiplication. They model and represent unit fractions. They represent money values in various ways. Students identify symmetry in the environment. They match
positions on maps with given information. Students recognise angles in real situations. They interpret and compare data displays.
Students count to and from 10 000. They classify numbers as either odd or even. They recall addition and
multiplication facts for single-digit numbers. Students correctly count out change from financial transactions.
They continue number patterns involving addition and subtraction. Students use metric units for length,
mass, and capacity. They tell time to the nearest minute. Students make models of three-dimensional objects.
Students conduct chance experiments and list possible outcomes. They carry out simple data investigations
for categorical variables.
- 2 Number: All About Fraction
Students had completed a unit of work on fractions, looking at fractions as part of a whole and fractions as part of a
collection. They also investigated which fractions are bigger and smaller and where they fit on a number line.
Students were asked to choose a fraction and record everything they knew about it. They were given access to all
