How many hundreds are there in
1,000?

This question mentions two
numbers. The first number is hundreds. Let’s remind ourselves what a
hundred is. It’s a one followed by two zeros,
isn’t it? It has a one in the hundreds place,
a zero in the tens place, and a zero in the ones place. And we can model 100 using one of
these place value blocks. The second number in our question
is written using digits. It’s made up of a one followed by
three zeros this time. This time, the one is in the
thousands place, and it has zeros in the hundreds, tens, and ones places. And because of that one in the
thousands place, we read this number as 1,000. And 1,000 using place value blocks
looks like one of these.

And our question asks us, how many
hundreds are there in 1,000? Let’s go through two ways to find
the answer. Firstly, we could use a place value
grid to help us, and we need to use what we know about each column. The lowest-value column, of course,
is the ones. And we can have anywhere from zero
ones up to nine ones. But because each column only
contains one digit, if we want to show 10 ones, we have to move to the next column
along because 10 ones is the same as one 10. And the same is true of the
tens. This place can only contain one
digit. So again, we could have anything
from zero all the way up to nine 10s. But as soon as we have 10 10s or
even more, we can’t show this. Again, we move up to the next
column. 10 10s are the same as 100.

Perhaps you can see where this is
taking us. Each time we find 10 of something,
we move to a new place value. A number can contain anywhere from
zero hundreds up to nine 100s. But as soon as we get to 10 100s,
we start a new column. 10 100s are the same as 1,000.

So that’s one way to find the
answer. But we could also use place value
blocks. We could ask ourselves, how many of
these could we put together to make one of these? Let’s find out. We’d need one, two, three, four,
five, six, seven, eight, nine, 10. We’ve used a place value grid and
place value blocks to work out how many hundreds there are in 1,000. But there are other ways we
could’ve found the same answer. For example, we could’ve shown how
we can count in hundreds 10 times before we get to 1,000. There are 10 100s in 1,000.
