My 1912 book "Practical Selections" has this poem for teaching kids to tell time... How to Tell the Time I've jus' learned how to tell the time, My mother teached me to, An' ef you think you'd like to learn, I guess I might teach you; At first, though, it's as hard as fun. An' makes you twist and turn, An' mother says that they is folks, Big folks, what never learn. You stand before the clock, jus' so, An' start right at the top; That's twelve o' clock, an' when you reach The little hand you stop; Now, that's the hour, but you've got To watch what you're about, Because the hardest part will come, To find the minutes out. You go right back again to where You started from, an' see How far the minute-hand's away, Like this -you're watchin' me!- An' when you've found the minute-hand You multiply by five-- And then you've got the time of day As sure as you're alive. They's folks, I know, what says that they Don't have to count that way, That they can tell by jus' a glance At any time o' day; But I don't believe no fibs like that, Because ef that was true, My ma would know it, but she showed Me like I'm showin' you. - W.
