Place Value in Three-Digit Numbers We write the number name for a three-digit number by naming the hundreds first. Then we name the tens and ones together.For example, the number name for 542 is five hundred forty-two.Write the number shown by the models.

Expanded FormTo write three-digit numbers in expanded form,we write the hundreds plus the tens plus the ones. The expanded form of 358 is 300 + 50 + 8.Write the number in expanded form. 1. 2. 263 = + + 415 = + +3. 4.532 = + + 328 = + +Chapter 5 Lesson 7 CCSS2.NBT.3 15

Comparing NumbersTo compare three-digit numbers, first compare the hundreds.If the hundreds are the same, compare the tens.If the tens are the same, compare the ones.If all three digits are the same, the numbers are equal.279 > 258 258 < 279 279 is greater than 258. 258 is less than 279.Write how much. Compare. Write >, <, or =. 1.2.
