Children are curious by nature. They have questions about the anything and everything in the world. Say, for instance, your little kid innocently asks, “what is the round thing on the wall with numbers and two hands?” You’d say, “it’s a clock” Then pat comes another question, “what ‘s a clock?” Fortunately, there’s the hickory dickory nursery rhyme to save you the trouble of answering this question, at least. This kiddies song is about a mouse that ran up a clock, only to fall or climb down or run away every time until the clock struck 12. It’s the best way to teach kids the numbers as well the functioning of the clock. We love such rhymes, don’t you?
