Data representation

This Content Descriptor from Year 5 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

explain how digital systems represent all data using numbers

Elaborations

• representing data using whole numbers and recognising this is how digital systems represent data, for example converting letters in a message to numbers using their position in the alphabet
• explaining how the data type used to represent data changes the operations that can be performed on it, for example adding numbers performs addition whereas adding strings joins them

Year 5 Technologies Achievement Standard

By the end of Year 6 students develop and modify digital solutions, and define problems and evaluate solutions using user stories and design criteria. They process data and show how digital systems represent data. Students design algorithms involving complex branching and iteration and implement them as visual programs including variables. They securely access and use multiple digital systems and describe their components and how they interact to process and transmit data. Students select and use appropriate digital tools effectively to plan, create, locate and share content, and to collaborate, applying agreed conventions and behaviours. They identify their digital footprint and recognise its permanence.
