• ### Choose the correct expanded form.

Hints

Say the number 873 out loud slowly. What did you hear? How many hundreds, tens, and ones?

Remember, all hundreds are followed by two zeros. For example: 100, 200, 300, 400, 500, 600, 700, 800, 900.

Remember, the tens place is a number followed by one zero. For example, the numbers 10, 20, or 30.

Look at the hundreds, tens, and ones in 873.

Solution

The correct expanded form for 873 is 800 + 70 + 3. This number had 8 hundreds (800), 7 tens (70), and 3 ones (3).

• ### Match each number correctly.

Hints

Remember, the expanded form shows the amount of hundreds, tens, and ones a number has.

Look at this example of expanded form:

700 + 60 + 2 = 762

Solution

All numbers expand to show the amount of hundreds, tens, and ones. When these hundreds, tens, and ones come together, we have a 3 digit number.

• ### What is 612 in expanded form?

Hints

Think about place value when writing the hundreds, tens, and ones.

Look at this example. 513 in expanded form is 500 + 10 + 3.

Solution

The expanded form for 612 is 600 + 10 + 2.

• ### What is this number?

Hints

Look at the number of hundreds, tens, and ones. Say them out loud.

If there were 3 hundreds, 5 tens, and 1 one, the number would be 351.

Solution

This number is 463. There are 4 hundreds (400), 6 tens (60), and 4 ones (4).

• ### Show the hundreds, tens, and ones.

Hints

Remember to give the hundreds, tens, and ones their appropriate place values. Example: 692 = 600 + 90 + 2

Count the hundreds out loud, then look for the matching number. Do the same with the tens and ones.

Solution

The number 384 has 3 hundreds, 8 tens, and 4 ones. The expanded form is: 300 + 80 + 4.
