  1. Place Value:Expanded Notation Lesson 5

  2. Math Vocabulary Place Value The name of the “place” where a digit is within a given number e.x. 456,722 7 = hundreds place value Expanded Notation “Expanding” a number (making it longer) by naming each digits place value

  3. Place Value Place Value is… _ _ _, _ _ _, _ _ _, _ _ _ . *place value of whole numbers is identified by “backwards” order; reading right to left

  5. Expanded Notation… 1 millions + 2 hundred thousands + 3 thousands + 4 hundreds + 7 ones **0’s do NOT need to be identified, unless asked for Write in “expanded notation”: 1,203,407

  6. Practice: Write each number in expanded notation: • 2,519 • 6,006,600
