OUTCOME
A student:
MA2-13MG: reads and records time in one-minute intervals and converts between hours, minutes and seconds
TEACHING POINTS | Midday and midnight need not be expressed in am or pm form. ’12 noon’ or ’12 midday’ and ’12 midnight’ should be used, even though 12:00 pm and 12:00 am are sometimes seen. |
| The terms ‘am’ and ‘pm’ are used only for the digital form of time recording and not with the ‘o’clock’ terminology. | |
| It is important to note that there are many different forms used in recording dates, including abbreviated forms. | |
| Different notations for dates are used in different countries, eg 8 December 2014 is usually recorded as 8/12/14 in Australia, but as 12/8/14 in the United States of America. | |
| Refer also to background information in Time 1. |
LANGUAGE | Students should be able to communicate using the following language: calendar, date, timetable, timeline, time, hour, minute, second, midday, noon, midnight, am (notation), pm (notation). |
| The term ‘am’ is derived from the Latin ante meridiem, meaning ‘before midday’, while ‘pm’ is derived from the Latin post meridiem, meaning ‘after midday’. |
EXPECTATIONS OF ATTAINMENT
Convert between units of time (ACMMG085) | convert between units of time and recall time facts, e.g. 60 seconds = 1 minute, 60 minutes = 1 hour, 24 hours = 1 day |
explain the relationship between the size of a unit and the number of units needed, eg fewer hours than minutes will be needed to measure the same duration of time {Communicating, Reasoning, Critical and creative thinking} |
Use am and pm notation and solve simple time problems (ACMMG086) | record digital time using the correct notation, including am and pm, e.g. 9:15 am {Literacy} |
| – describe times given using am and pm notation in relation to ‘midday’ (or ‘noon’) and ‘midnight’, eg ‘3:15 pm is three and a quarter hours after midday’ {Communicating, Literacy} | |
| relate analog notation to digital notation for time, eg ten to nine in the morning is the same time as 8:50 am {Literacy} | |
| solve simple time problems using appropriate strategies, eg calculate the time spent on particular activities during the school day {Critical and creative thinking} |
Read and interpret simple timetables, timelines and calendars | read and interpret timetables and timelines {Literacy, Critical and creative thinking Personal and social capability} |
| read and interpret calendars {Literacy, Critical and creative thinking Personal and social capability} | |
| – explore and use different notations to record the date {Communicating, Literacy, Critical and creative thinking Personal and social capability} | |
| – explore and use the various date input and output options of digital technologies {Communicating, Information and communication technology capability, Personal and social capability} |
