Worked example. Name the place of each digit in 658.
6 is in the hundreds place (600), 5 is in the tens (50), 8 is in the ones (8).
Worked example. Write 503 in expanded form.
503 = 500 + 0 + 3 = 500 + 3. There are no tens, so we just show the hundreds and ones.
Worked example. Which is bigger, 318 or 381?
Both have 3 hundreds. Tens: 381 has 8 tens, 318 has 1 ten. So 381 is bigger.
