Arrange the following in ascending
order: 3838, 2865, 1139, and 5206.
When something ascends, it rises or
goes up. And so, if we put a series of
numbers in ascending order, we arrange the numbers so that they go up from least to
greatest value. And that’s what we need to do with
the four numbers we’ve been given here: 3838, 2865, 1139, and also 5206.
Now, often, when we compare numbers
like this, we might write them in a place value grid and compare the digits from
left to right in order of how large they are. But with these four numbers, we
don’t have to do this. Why is this? Well, if we look quickly at the
digit with the largest value in these numbers, which is the thousands digit, we can
see that they’re all different. This means that we can put these
numbers in order really quickly just by looking at this one digit. Which number has the least amount
of thousands? It’s the third number in our
list. It only has 1000. So, the smallest number, the one
with the least value, is 1139.
Now that we’ve used this number,
which of the remaining three numbers has the least amount of thousands now? It’s our second number. This only has two thousands. So, the second number in our list
is going to be 2865. And by looking at our two remaining
numbers, we can see that the first has three thousands and the second contains
five. Three is obviously less than
five. So, the next number in our list is
3838. And the greatest of our four
numbers is the one that contains five thousands, 5206.
Each of the four-digit numbers that
we looked at had a different number of thousands. As the thousands place in a number
is the place with the greatest value, we could just look at the digit in this place
and put the numbers in order straightaway. And so, our four numbers in
ascending order — that’s from least two greatest value — are 1139, 2865, 3838, and
