Place Value Through Hundred Thousands

Objective

• By the end of this lesson, you will be able to
  read and write whole numbers to the hundred
  thousandths.
• Standard 4NS1.1 Students will read and write
  whole numbers in the millions.

3
Introduce

• We are going to play a game called Eliminator.
• You are going to draw 6 small lines on your
  whiteboards.
• I am going to roll a die, and after each time you
  are going to place that number on one of the
  lines.
• The goal is to create the largest 6-digit number
  that you can.
• Also, draw a box under your lines. This box
  allows you to place one of the numbers you do not
  like in it one time.

Teach

• 184,800

• How many ten thousands are there?
• How many thousands are there?
• How many hundreds are there?
• How many tens are there?
• How many ones are there?
• What is the value of each digit in this number?

Understanding Place Value

• In 2004, the number of Labrador retrievers
  registered with the American Kennel Club was 146,
  692.
• What is the value of the digit 4 in 146, 692?
• Lets look at a place value chart to help us
  understand the value of each digit in a number.
• Remember - the value of a digit depends on its
  place-value position in the number!!

Period

• I thought we only used periods for sentences!
• A period is a group of three digits separated by
  a commas in a large number.
• These periods help when writing in different
  forms. They help reading and writing numbers
  correctly.
• Every period is separated by a comma.

The Three Different Forms

• Standard Form - the actual number
• Example 146,692
