• Using simple time periods, I can give a good estimate of how long a journey should take, based on my knowledge of the link between time, speed and distance.
• Reads and records time in both 12 hour and 24 hour notation and converts between the two.
• Knows the relationships between commonly used units of time and carries out simple conversion calculations, for example, changes 1 3/4 hours into minutes.
• Uses and interprets a range of electronic and paper-based timetables and calendars to plan events or activities and solve real life problems.
• Calculates durations of activities and events including situations bridging across several hours and parts of hours using both 12 hour clock and 24 hour notation.
• Estimates the duration of a journey based on knowledge of the link between speed, distance and time.
• Chooses the most appropriate timing device in practical situations and records using relevant units, including hundredths of a second.
• Selects the most appropriate unit of time for a given task and justifies choice.
