This question can be given to students who
are learning decimal units to provide basic calculations and provide an
assessment of a very large number. A simple question that challenges to
stimulate simple assessment one of which is as follows.
I want to count to one million.1, 2, 3, 4, 5, ...How long does it take?
Of course, this is an open-ended question.
The answer could be a variety of conditions. It could be when spell is interspersed stop, or can also be in spell the numbers constantly. In the case of
simple assessment, it can be said that the number takes about one second to
be spelled, and if they do not stop counting until finished it will take
about one million seconds.
As a sequel, in terms of studying the
decimal unit, then be directed to the state of one million seconds into a
simpler form, for example by converting into units of minutes, hours, or days.
These issues provide a good opportunity to emphasize the ability of the
assessment.
1,000,000 seconds to change to the day we
need to calculate:
For a quick calculation, round 24 to 25, so
that:
Because more than 10, then a good estimate
is 11 days. The real answer is approximately 11 ½ days.
