Sixteen three-digit numbers to write in expanded form: 365 = 300 + 60 + 5. Children read the digit in each place and write what it is worth, so the 3 becomes 300 and the 6 becomes 60. None of the numbers has a zero digit, so every answer has three parts; numbers with zeros are on the place value chart sheet.
