builDiNg 4-Digit Numbers

We use groups, like ones, tens, hundreds and thousands to build a 4-digit number.

Note
th H t O Do not add an ‘s’ after the
1,000 + 200 + 40 + 2 = 1 2 4 2 name of the place while

1,242 is read as 'one thousand two hundred forty-two.' reading/writing number names.

th H t O
3,000 + 400 + 10 + 6 = 3 4 1 6
3,416 is read as 'three thousand four hundred sixteen.'

Look at the pictorial representations of some more 4-digit numbers.

(a)

th H t O
2,000 + 400 + 70 + 3 = 2 4 7 3
Two thousand four hundred seventy-three

Think and Answer
1. There are ___ hundreds
in one thousand.
(b) 2. There are ___ tens in
one thousand.

th H t O
6,000 + 100 + 50 = 6 1 5 0
Six thousand one hundred fifty

(c)

th H t O
3,000 + 30 + 8 = 3 0 3 8
Three thousand thirty-eight

Remember
Š We put a zero (0) to fill in places where no place value is mentioned.
Š In a 4-digit number, if there is 0 at the hundreds, tens or ones place, we do not mention it in
the number name.
