Parents constantly tell kids to wait a minute. But little ones don\u2019t always understand what that means or that a minute is a measure of time. By the time they are\u00a04 years\u00a0old,\u00a0children\u00a0start to understand concepts like\u00a0\u201cbefore lunch\u201d\u00a0or\u00a0\u201cafter we go to the store.\u201d Actual \u201cclock times\u201d\u00a0are still challenging to comprehend. Educators say\u00a0that\u00a0you can help preschoolers learn by\u202fassociating events\u00a0\u2014 such as meals, bath time and bedtime \u2014\u00a0 with time.\u00a0For example, say things like, \u201cIt\u2019s time to brush your teeth\u00a0before\u202fwe go to Grandma\u2019s house\u201d or \u201cWe will have dinner tonight\u202fafter\u202fDaddy comes home from work.\u201d When it comes time to actually teach children how to\u202ftell time\u202f(ages 4-6), the choices of how to do so are endless. Dozens of devices have been used over the centuries, including\u00a0candles, hourglasses, sundials, clocks with gears, watches, clock towers and astronomical clocks. Digital clocks are probably the easiest with which to teach once little ones can identify numbers. Repetition helps, so say things like, \u201cWe eat lunch at 12:00\u201d or \u201cIt will be time to go to bed at 7:00.\u201d\u00a0 The most familiar tools to identify on a traditional clock are the big and little hands on its face. So, say something like, \u201cWhen the little hand is on the 6 and the big hand is on the 12, Mommy will be home.\u201d\u202f\u00a0 As we approach a new year, there is\u00a0another fun way to explain time:\u00a0with a countdown to the new year. The biggest water clock in North America can be found at The Children\u2019s Museum of Indianapolis. There, families can watch the neon green and bright blue clock drip down,\u00a0drop by drop,\u00a0to a new year on Dec. 31, 2019. The clock stands 26.5 feet tall and will help\u00a0welcome\u00a02020 at the family-friendly hours of\u00a012 pm and 1 pm. There will be a live band and New Year\u2019s Eve swag while supplies last. Families who can\u2019t join that celebration can visit most days to\u00a0listen to\u00a0an actor interpreter explain\u00a0in a kid-friendly way\u00a0how time works with the water clock. The big orb-shaped balls represent one hour and the smaller discs represent two minutes. When it\u2019s time to move forward to a new hour, visitors watch the water drain from the tubes to fill a new orb. Brought to you by the Children's Museum of Indianapolis.
