Write the letters for the times in order, starting with the earliest. What time did he finish? Give your answer using digital 24-hour clock time.Ĥ. What is the time on Lily’s clock face?ģ. Toby went to cubs at 7pm. Lily says, ‘On my clock face, the big hand is on the 4 and the little hand is between the 8 and the 9’. 12 hour clock & 24 hour clock worksheet questionsĢ. Convert 24-hour time to 12-hour time easily. ![]() 24-hour to 12-hour Time Conversion Chart You can use this chart to convert 24-hour time to 12-hour time format and vice versa. How do the 12- and 24-hour clock relate to other areas of maths?Ĭhildren are sometimes required to read and interpret timetables (such as timings of a school day, or a bus timetable) which will often use timings either written in the 12- or 24-hour clock. From 13:00 to 23:59: Subtract 12 and add PM You can also use a 24-hour clock converter with minutes for the 24-hour to 12-hour time conversion. There are no specific objectives about time in upper KS2. In this way they become fluent in and prepared for using digital 24-hour clocks in year 4, where they will then learn to read, write and convert time between analogue and digital 12- and 24-hour clocks. The National Curriculum’s non-statutory guidance also advises that pupils use both analogue and digital 12-hour clocks and record their times. 12 hour and 24 hour clock in KS2Ĭhildren’s learning of time is continued into lower KS2, where they will tell and write the time from an analogue clock, including using Roman numerals from I to XII, and 12-hour and 24-hour clocks (Year 3). In KS1 pupils will learn to tell the time to the hour and half past the hour and draw the hands on a clock face to show these times (Year 1) and tell and write the time to five minutes, including quarter past/to the hour and draw the hands on a clock face to show these times (Year 2). 3pm becomes 15:00 because 3 + 12 = 15.Īn example of a Third Space Learning lesson slide on converting between 12 and 24-hour clock When will my child learn about the 12-hour and 24-hour clock in primary school? 12 hour and 24 hour clock in KS1 To convert from a 12-hour clock to a 24-hour clock, children may be taught to add 12 to the hours after midday, e.g. ![]() How to convert from a 12-hour clock to a 24-hour clock? For example, 0300 = 3rd hour of the day, or 3am 1400 = 14th hour of the day, or 2pm 1830 = 30 minutes past the 18th hour of the day, or 6.30pm. as each time represents each hour in a 24-hour day. The 24-hour clock is more often shown on digital clocks and is written in a 4-digit form, with the first two digits representing the hour and the last two representing the minutes. (‘post meridiem’ – Latin for ‘after midday’). (‘ante meridiem’ – Latin for ‘before midday’) or p.m. The 12-hour clock is most commonly represented on an analogue clock with the numbers 1-12 when shown on a digital clock, it is usually accompanied by a.m. If you don't want to use a conversion calculator (like the one above), another basic tool is a decimal conversion chart. When you have to turn, say, 17 hours and 25 minutes in decimals, you can easily check the conversion table and see that this equals 17.42 hours.This article summarises what primary school pupils in KS1 and KS2 will be taught about the 12-hour clock and 24-hour clock and provides some telling the time questions for children to practise telling digital and analogue time on digital and analogue clocks. Manually converting employee hours and minutes to decimal values (hundredths) is time-consuming and prone to errors. Minutes to Decimals Time Conversion Chart To get her net pay, you'll have to factor in deductions and taxes. Melanie’s weekly pay based on her total hours is then: 37.7 hours x $15 = $565.50 This means that 37 hours and 42 minutes convert to 37.7 hours in decimal time. Then you have to add the converted minutes to the hours: 37 + 0.7 = 37.7 The correct calculation is thus: 42 minutes/60 = 0.7 ![]() You have to convert minutes into decimals. This is wrong since, once again, an hour is made up of 60 minutes, and not 100. However, if you take 37 hours and 42 minutes as they are, you would get 37.42. Then you need to multiply the number of hours she worked by her hourly rate to determine her weekly total pay. The hourly rate that she receives is $15.įirst, you have to take the information from her weekly time card or timesheet that contains her clock-in and clock-out times (ee timecard templates here). This week she has worked 37 hours and 42 minutes (and no overtime hours). It is also essential for keeping track of lunch breaks, general break time, overtime pay, and holidays. ![]() This is crucial for hourly staff members, who are often non-exempt employees. You need to convert time into decimal numbers to figure out your employees' exact pay rate. Why? Because one hour contains 60 minutes, and not 100. But hours and minutes aren’t directly equal to money owed. Usually you get records of employees’ time worked in hours and minutes. Wait…so why do I need time clock conversion?
