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

acquire data for categorical variables through surveys, observation, experiment and using digital tools; sort data into relevant categories and display data using lists and tables

Elaborations

• posing a question of interest about favourite things; for example, asking classmates what are their favourite types of fruit, football teams, days of the week, and recording responses using a table; using counting strategies to determine the number of different responses and the most popular and least popular responses
• investigating questions, such as “How much rubbish is really rubbish?” by gathering data about objects in categories; for example, throw away, recycle and reuse; deciding whether the data answers the question
• using familiar software or generative artificial intelligence tools, to construct a survey to collect class data, sorting and interpreting responses, and considering the questions asked and whether they need to be modified to reuse the survey
• observing events and using the observations to design a table or list to record data; for example, observing students arriving at school prior to deciding the appropriate data categories for investigating the different ways students get to school
• exploring the ways First Nations Australians observe, collect, sort and record data

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.
