Experience & Outcome: MNU 2-10a use and interpret electronic and paper-based timetables and schedules to plan events and activities, and make time calculations as part of my planning. recognise types of timetables and explain their purpose. Select appropriate timetables for a purpose. Use your own timetable to identify every time you have a maths class. Plan a journey from Selkirk to Edinburgh by bus. Plan a visit to the swimming pool for the fun session on a Friday after school. Use the music rotas to find out which day guitar lessons take place. create a timetable for purposes. Organise your events in time order. A school trip. An evening of your favourite television programmes. A rehearsal plan. To cook a two course meal. read and record time using 12 and 24 hour times. To convert to the 24 hour clock, if it is before 12 noon, add a 0 before the hours number and if it is after 12 noon, add 12 to the hours number. Identify the difference between am and pm. Identify the similarity between times in a 12 hour clock and a 24 hour clock 6.00 pm = 1800 hours. Recognise that the 12 hour clock am times and the 24 hour clock times are the same 1.00 am = 0100 hours. Recognise that to convert 12 hour clock pm times to 24 hour clock times, you add 12 to the number to convert 2.00 pm to 24 hour clock time = 2 + 12 = 14. Therefore, 2.00 pm = 1400 hours. work out the duration of activities / journeys. Work out how long in minutes/hours activities last. Period 3 starts at 10.55 am and ends at 11.45 am, how long does the period last? 5 + 45 = 50 minutes Lunch time on a Wednesday. Lunch time on a Friday. A double period of P.E. A standard rugby or hockey match. Think 5 minutes until 11 am and 45 minutes until 11.45 am
Experience & Outcome: MNU 2-10b carry out practical tasks and investigations involving timed events and can explain which unit of time would be most appropriate to use. select and use appropriate units of time for an event or activity. 100 m sprint seconds 5K run minutes A marathon hours and minutes Bus to Edinburgh hours and minutes Flight to Florida hours place the units of time in order. Organise the activities according to the time they take. a television advert - a blink of the eye - a school day A television advert lasts around 20 seconds A blink of the eye lasts a fraction of a second A school day lasts around 7 hours Think about how long each activity would take Therefore the correct order is: a blink of the eye a television advert a school day read and record time with correct notation. When reading time, use the whole word not the abbreviation. When recording time, use h, min and s. Use a stopwatch to record time in a 100 m race 30 seconds. Doing your homework 1 hour Watching television 1 hour 20 minutes. 2
Experience & Outcome: MNU 2-10c Using simple time periods, give a good estimate of how long a journey should take, based on my knowledge of the link between time, speed and distance. compare speed between types of transport. Order these modes of transport from slowest to fastest. Order these modes of transport from slowest to fastest if they were travelling over a period of an hour: car horse train aeroplane horse car train - aeroplane select the appropriate type of transport when planning a journey. Think of the distance and time available, choose the most appropriate. Which mode of transport would you choose from the following if you wanted to travel from Edinburgh to Madrid? Give reasons for your answer. train bike car aeroplane Aeroplane is most appropriate as the distance is large and the time taken to travel by other modes would be too long. estimate a length of time in a range of problem solving contexts. Round numbers to make the sum easier. If it takes two hours to get to Edinburgh - 35 miles away - by bus, how long will it take to travel 100 miles by the bus? 100 miles is approximately 3 x 35 So, it should take 2h x 3 = 6h 3
Experience & Outcome: MNU 3-10a Using simple time periods, work out how long a journey will take, the speed travelled at or distance covered, using my knowledge of the link between time, speed and distance. interpret a distance time graph. The blue line is steeper than the red which indicates a faster speed. change minutes to a decimal fraction and vice versa. To convert minutes into a decimal fraction of an hour, divide by 60 To convert a decimal fraction of an hour to minutes, multiply by 60. 15 min 15 60 = 0.25h 50 min 50 60 = 0.83h 0.4h 0.4 x 60 = 24 min 2.7h 0.7 x 60 = 42 min 2h 42 min calculate a time period given the start and finish times. Count the number of minutes from the starting time to next full hour. Count the number of hours from that hour to the finishing hour. Count the number of minutes to the finishing time. How long from 9.35 am to 3.08 pm? 9.35 am to 10 am = 25 min 10 am to noon = 2h Noon to 3.08 pm = 3h 8 min = 5h 33 min 4
calculate average speed, time and distance in a problem solving context. Convert the time given to the same units as the question e.g. hours for mph. Use the equation speed = distance time to calculate speed. A car leaves Selkirk at 0915 hours and arrives in Edinburgh, 35 miles away, at 1027 hours. What was the car s average speed in mph? Time: 0915 1015 = 1h 1015 1027 = 12 min = 1h 12 min 1.2h Speed = distance time: S = D T S = 35 = 29.16 29mph 1.2 5
