# Mathematics

## Proficiencies

**Understanding **includes connecting number calculations with counting sequences, partitioning and combining numbers flexibly, identifying and describing the relationship between addition and subtraction and between multiplication and division.

**Fluency** includes counting numbers in sequences readily, using informal units iteratively to compare measurements, using the language of chance to describe outcomes of familiar chance events and describing and comparing time durations.

**Problem Solving** includes formulating problems from authentic situations, making models and using number sentences that represent problem situations, and matching transformations with their original shape.

**Reasoning** includes using known facts to derive strategies for unfamiliar calculations, comparing and contrasting related models of operations, and creating and interpreting simple representations of data.

## Achievement Standard

By the end of the year students are expected to:

- recognise increasing and decreasing number sequences involving 2s, 3s and 5s;
- represent multiplication and division by grouping into sets;
- associate collections of Australian coins with their value;
- identify the missing element in a number sequence;
- recognise the features of three-dimensional objects;
- interpret simple maps of familiar locations;
- explain the effects of one-step transformations;
- make sense of collected information;
- count to and from 1000;
- perform simple addition and subtraction calculations using a range of strategies;
- divide collections and shapes into halves, quarters and eighths;
- order shapes and objects using informal units;
- tell time to the quarter hour and use a calendar to identify the date and the months included in seasons;
- draw two- dimensional shapes;
- describe outcomes for everyday events;
- collect data from relevant questions to create lists, tables and picture graphs.
