Year 2 Mathematics Achievement Standard – Australian Curriculum v9
This Achievement Standard describes what students are expected to know and do in Year 2 Mathematics by the end of the year. Teachers can use it to guide assessment design, collect evidence of learning, and ensure planning stays aligned with the Australian Curriculum v9.
What Students Should Know
By the end of Year 2, students order and represent numbers to at least 1000, apply knowledge of place value to partition, rearrange and rename two- and three-digit numbers in terms of their parts, and regroup partitioned numbers to assist in calculations. They use mathematical modelling to solve practical additive and multiplicative problems, including money transactions, representing the situation and choosing calculation strategies. Students identify and represent part-whole relationships of halves, quarters and eighths in measurement contexts. They describe and continue patterns that increase and decrease additively by a constant amount and identify missing elements in the pattern. Students recall and demonstrate proficiency with addition and subtraction facts within 20 and multiplication facts for twos.
They use uniform informal units to measure and compare shapes and objects. Students determine the number of days between events using a calendar and read time on an analog clock to the hour, half hour and quarter hour. They compare and classify shapes, describing features using formal spatial terms. Students locate and identify positions of features in two-dimensional representations and move position by following directions and pathways.
They use a range of methods to collect, record, represent and interpret categorical data in response to questions.
