4 A student: communicates and connects mathematical ideas using appropriate terminology, diagrams and symbols MA41WM applies appropriate mathematical techniques to solve problems MA42WM performs calculations of time that involve mixed units, and interprets time zones MA415MG Related Life Skills outcomes: MALS-20MG, MALS-21MG, MALS-22MG, MALS-23MG, Students: Solve problems involving duration, including using 12-hour and 24-hour time within a single time zone (ACMMG199) add and subtract time mentally using bridging strategies, eg from 2:45 to 3:00 is 15 minutes and from 3:00 to 5:00 is 2 hours, so the time from 2:45 until 5:00 is 15 minutes + 2 hours = 2 hours 15 minutes add and subtract time with a calculator, including by using the 'degrees, minutes, seconds' button round answers to time calculations to the nearest minute or hour interpret calculator displays for time calculations, eg 2.25 on a calculator display for a time calculation means hours or 2 hours 15 minutes solve a variety of problems involving duration, including where times are expressed in and 24-hour notation, that require the use of mixed units (years, months, days, hours and/or minutes) Solve problems involving international time zones compare times in, and calculate time differences between, major cities of the world, eg 'Given that London is 10 hours behind Sydney, what time is it in London when it is 6:00 pm in Sydney?' interpret and use information related to international time zones from maps (Problem Solving) solve problems involving international time as it relates to everyday life, eg determine whether a particular soccer game can be watched live on television during normal waking hours (Problem Solving)
