Math Activities with Clocks

Clocks are useful and the ability to read an analog clock is a skill many kids (and some adults) struggle with.  Today I'll give some activities and things to do with the 12-hour analog clock and the 24-hour clock.
  • Above is the 12-hour standard analog clock, assuming we are using AM and PM times. (Thanks to French homeschooling website for the image).
    • Use the above image to draw a certain time.
      • I have a stamp like this one where I made a memory game.
      • Show what it means to go clockwise and counter-clockwise.  (right and left, directions)
    • You can use the image above as a pie graph to chart the time a child works on a chore or a task (For example: if a child reads for 10 minutes fill in a pie piece from 12-2).
    • Do a Google image search of "analog clocks" and see if you can read all the times.
    • You can talk about time zones and how different places in the world are at a later or earlier time than yourselves.
You can talk about 24-hour clocks.  There are 24 hours in a day after all.  Many parts of the world use the 24-hour time.
    • With either the 12-hour or 24-hour clock you can list activities you are doing during certain times of the day.
      • Talk about schedules and length of activities that your favorite hobbies take...How long does a soccer game last?  Are there breaks between these sports--quarters, half-times? (You're talking about fractions and you probably don't even realize it.)
    • Did you know there is another way the 24-hour clock can be seen other than the analog and digital?  Have you heard of a binary clock?
I didn't know about them until my husband got one as a Christmas present.  He showed me and the kids how to read it.  This is the best tutorial I found about it...    Watch "Binary Clock Tutorial" on YouTube
I guess you can get the binary clock app for your smart phone too...
    • When learning about the binary clock there is a good kids book that describes what binary numbers are in good detail.  It's...
    • You might find it in your local library.  I found it very informative (although it may take a few days to go through with your child or class).  It is a fascinating subject and may intrigue your young student too.
What is your favorite clock type? Analog or digital?  Do you use a 24-hour clock?
