let's look at the clock and see what time is shown the clock has two hands this first shorter one which represents the hours and then there's a longer hand here that represents the minutes so we can start with the hours this shorter hand right here before we can figure out the hours you may have noticed our clock is not labeled so let's add some labels at the top of the clock here is always 12 o'clock that's where the hour hand starts and then the hour hand really only deals with these larger square marks so when it works its way to this first one then it is now one o'clock and when it gets to the next one 2 o'clock and 3 & 4 5 and so on until we work our way all the way back to 12 o'clock so now our hour hand let's look at our hour hand right here we can see it's just barely past the 10 but it hasn't reached 11 so that means our hour it's after 10 o'clock maybe 10:05 maybe 10:30 but it hasn't reached 11 yet so we can safely put a 10 in for our hours and now let's switch to minutes here's our minute hand and it looks like it's lined up to this little mark minutes are shorter and they also use these shorter marks on the clock minute hand starts facing up so when the minute hand was here it was 10 o'clock and then it moved 1 minute so it was one minute after 10 or 1001 and 1002 1003 1004 1005 so this is 5 minutes after 10 and it keeps going 1006 1007 1008 1009 1010 right here and maybe you can see this pattern it keeps going here it was 0 minutes after the hour so 0 then 5 and 10 so this one is going to be 15 we're going to keep counting by 5's and then one more minute after that is 16 so it is 10 16 or 16 minutes after 10 one more here let's again start with our our hand and we know our labels we know this is 12 1 2 we could keep labeling but our our hand is facing right there so we really don't need to our hand is between 1 & 2 so it's after 1 but not yet - so it's 1 something and by looking at our minutes we can see it's quite a bit after 1 this minute hand has worked its way around and remember this is me 5 minutes after 10 15 20 25 30 35 40 we can't go to 45 that's too far so let's go back to 40 and now just count by ones 41 42 43 44 our minute hand lines up here - 44 minutes after 1 o'clock or 144
