You can show numbers using
base-ten blocks to model
a number.
|
 |
This is the
1-block or
unit block the
smallest of all the blocks. |
|
 |
This is the
10-block
corresponding to 10 units.
It is also referred to as a
rod or long. |
|
 |
This is the
100-block and
corresponds to 100 units. It is also called a
flat. |
 |
This is the
1000-block and
corresponds to 1000 units. |
Here are some numbers represented using base ten blocks.
Numbers
are made up of digits in
the same way that words are made up of letters.
These words are called place
value headings.

hundreds |
tens |
ones |
|
3
3 x 100 = 300
 |
2
2 x 10 = 20
|
5
5 x 1 = 5
|
|
3 hundreds |
2 tens |
5 ones |
The number
325 is
made up of :
five
ones
two tens
and three hundreds
|
 |
Remember: To find the
value of each digit, multiply the digit by its
place-value position.
In 5,432 the value of
the 4 is 4 x 100, or
400. |
