1. Place Value Through Hundred Thousands

2. 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. 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. Introduce

4. Teach • 184,800 • How many hundred thousands are there? • 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?

5. 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? • Let’s 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!!
