Data representation

This Content Descriptor from Year 3 Technologies 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 different types of data and explore how the same data can be represented differently depending on the purpose

Elaborations

• describing different types of data and how they can be used, for example numbers, letters, symbols and pictures
•
explaining how the same data can be represented in different ways and why some representations are better than others in certain contexts, for example four vs 4 vs IV vs I I I I vs quatre and that numerals are better for calculation than words
• explaining that the same information can be represented differently, for example the term ‘stop’ can also be represented with an octagon-shaped red sign or a hand icon
• identifying rock paintings and other cultural expressions to understand that images are used to encode and represent ethnobotanical knowledge, for example the representation of plant use in the Kimberley cave paintings and ancient engravings including important data on medicinal and food plant classification and their usable parts

Achievement Standard This Supports

Year 3 ASTECTDIY34

Year 3 Technologies Achievement Standard

By the end of Year 4 students create simple digital solutions and use provided design criteria to check if solutions meet user needs. Students process and represent data for different purposes. They follow and describe simple algorithms involving branching and iteration and implement them as visual programs. Students securely access and use digital systems and their peripherals for a range of purposes, including transmitting data. They use the core features of common digital tools to plan, create, locate and share content, and to collaborate, following agreed behaviours. Students identify their personal data stored online and recognise the risks.
