  • 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.

  • What are the numbers in expanded form?

    Hints

    Remember, 3 digit numbers always start with the hundreds place.

    Remember, say the number out loud to hear how many hundreds, tens and ones it has.

    Solution

    The expanded form shows the hundreds, tens and ones.
