Today we are going to look in more detail at converting 12 hour and 24 hour time. We know that you have been working incredibly hard on measuring time over the past few weeks and. today. we would like you to take a look at both of the powerpoints in order to see how much you now understand from all the learning that you have been doing. After you have taken a look, you have the option of completing one of the differentiated worksheets ONLY if you feel confident to do so. A rule to remember when measuring 24 hour time is that the hour digits go from 00 (midnight) to 23 (11pm) and the minutes digits still start at 00 to 59. For example 00:01 is one minute past midnight (or the first minute of the new 24 hour day) and 23:59 is the last minute of the 24 hour day.
