Numbers really can be huge – some are too big to even imagine!  Have you ever seen a million pieces of candy? Or have you ever even tried to count to one million? In this video, we’ll try to figure out about how long it would take just to count to one million. I’ll also show you how to write some really big numbers!

So there are 31,536,000 seconds in a year, but you couldn’t spend all of your time counting. Simply saying larger numbers will take much longer than a second! So with lots of breaks for sleeping, eating, and homework, it would take more than a year to count to a million…and most people get bored with counting way before that.

Exercises

  1. How many seconds are there in one hour?
  2. How many seconds are there in a day?
  3. How many days does a leap year have?
  4. Write a number greater than but closer to a billion.(Note the difference between the two should be less than 50)
  5. Write a number lesser than but closer to a billion.(Note the difference between the two should be less than 50)

Write the following numbers out numerically:

  1. A thousand billion
  2. A thousand million
  3. A hundred hundred
  4. Write a number that is 1 less than 100,000,000,000

    There is 1.892e+11 seconds in sixty centuries

  2. Christina Galvan says:

    There are 3.154e+9 seconds in a century

  3. How would you figure this out? Here’s the setup:

    1 century = 100 years => (100 years) x (365 days/year) x (24 hours/day) x (60 minutes/hour) x (60 seconds/minute) = …?

    What do you find out?
