Unit focus

  • State the starting and finishing times, including am or pm and the day. Count forward in useful jumps through the next hour, noon or midnight.
  • Use 60 seconds = 1 minute and 60 minutes = 1 hour. Use groups of 60 when converting between these units, not groups of 100.
  • When planning a timetable, include activities, rests and any waiting time. Public cultural accounts can explain repeating Sun, Moon and star cycles; identify the particular community and source.
