Examine how whole numbers are used to represent all data in digital systems

Elaborations

  • recognising that digital systems represent all types of data using number codes that ultimately are patterns of 1s and 0s (called binary digits, which is why they are called digital systems) (Skills: Literacy, Numeracy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
  • explaining that binary represents numbers using 1s and 0s and these represent the on and off electrical states respectively in hardware and robotics (Skills: Numeracy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
  • recognising that the numbers 0, 1, 2 and 3 could be represented by the patterns of two binary digits of 00, 01, 10 and 11 (Skills: Numeracy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
  • representing whole numbers in binary, for example counting in binary from zero to 15, or writing a friend’s age in binary (Skills: Numeracy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
  • exploring how division by two can be used as a technique to determine the binary representation of any whole number by collecting remainder terms (Skills: Literacy, Numeracy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
  • representing the state of an object in a game as active or inactive using the respective binary values of 1 or 0 (Skills: Numeracy, Information and Communication Technology (ICT) Capability, Critical and Creative Thinking)
