What is the number represented
below?
The number that this question’s
talking about is represented by the place value grid that we can see. Let’s take a moment to look at it
carefully. What can we say about this
grid? Well, firstly, we can see that it’s
made up of four columns. This means that the number that we
can see is a four-digit number. Do you remember what place value
each one of these four columns represents? We’ve got our ones, tens, hundreds,
and then this final column here which represents thousands. And each 1000 is shown by one of
these green cubes here. They’re made by putting 10 100s
together, 100 10s, or even 1000 ones.
And we can see if we look at our
place value grid, we’ve modeled our number using two 1000s blocks and nothing
else. There are no little red ones blocks
in the ones column. Let’s write a zero to show there
aren’t any. And there are no tens rods in the
tens column. Again, let’s show a zero to show
that we haven’t got any tens or any hundreds. But we can see that we do have some
1000s blocks, and there are two of these. So, we can write the digit two in
the thousands place. Two 1000s have a value of 2000, and
that’s how we say our number, 2000.
Now we don’t have to do this, but
when we write a number in thousands, we can use a comma after the thousands and
before the hundreds digit to separate out the thousands. So instead of writing our answer
like this, we can write it like this. It’s just a way of helping us read
large numbers quickly. In the place value grid, we saw
that there were two 1000s blocks, and there wasn’t anything else. And that’s how we know the number
that’s represented in the place value grid is 2,000.
