This Content Descriptor from Year 2 Mathematics provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

Content Descriptor

recognise and read the time represented on an analog clock to the hour, half-hour and quarter-hour

Elaborations

• creating an analog clock from a paper plate, showing the placement of the numbers and the \(2\) hands; explaining how long it takes for the \(2\) hands to move around the clock face and what time unit each is showing
• recognising and describing the relationship between the movement of the hands on an analog clock and the duration of time it represents; for example, connecting the language of “half past” to mean when the “big hand” will be at half past the hour and recognising this position as being halfway around its full cycle
• dividing a clockface into halves and quarters, and connecting the subdivisions with telling the time to the half and quarter hour; explaining the meaning of “quarter past” and “quarter to” referring to the hour

Year 2 Mathematics Achievement Standard

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.
