Compose numbers from hundreds, tens, and ones

A three-digit whole number is composed by combining its hundreds, tens, and ones values: for example, 4 hundreds, 2 tens, and 7 ones represent 427, or $400+20+7$ . This understanding includes interpreting zero as an empty place when a number lacks tens or ones, connecting standard, expanded, and place-value representations, and recognizing that a digit’s value depends on its position; larger numbers and more advanced place-value generalizations are not included.

Detailed Explanation: Compose numbers from hundreds, tens, and ones

A three-digit number is made of:

Hundreds: groups of 100
Tens: groups of 10
Ones: single units

To compose a number, find the value of each place and put the digits in the correct order: hundreds, tens, ones.

Example: Compose a number with 3 hundreds, 0 tens, and 6 ones.

The 3 hundreds have a value of $300$ .
The 0 tens have a value of $0$ .
The 6 ones have a value of $6$ .
Add the values:

300+0+6=306

So, 3 hundreds, 0 tens, and 6 ones make $306$ .

The zero shows that there are no tens. In $306$ , the digit $3$ means 3 hundreds, the digit $0$ means 0 tens, and the digit $6$ means 6 ones.
