Place value is the value of a digit based on its position in a number. For example, in the number 345, the digit 3 is in the hundreds place, meaning it represents 300. The digit 4 is in the tens place, representing 40, and the digit 5 is in the ones place, representing 5. Understanding place value helps us read, write, and compare numbers accurately.
Let's take the number 672. To understand its place value, we can break it down: 6 is in the hundreds place (600), 7 is in the tens place (70), and 2 is in the ones place (2). So, 672 can be expressed as 600 + 70 + 2. This breakdown helps us see how each digit contributes to the overall value of the number.
Now, let's practice together! I will write a number on the board: 854. Can anyone tell me what the place value of the digit 8 is? (Pause for responses.) That's right! The 8 is in the hundreds place, so it represents 800. What about the digit 5? (Encourage students to respond.) Correct! The 5 is in the tens place, representing 50. Finally, what does the 4 represent? (Wait for answers.) Exactly! The 4 is in the ones place, so it represents 4.
Now it's your turn! Solve the following problems on your own: 1. What is the place value of the digit 3 in the number 3,482? 2. Write the number 1,205 in expanded form. 3. If you have the number 920, what is the value of the digit 9? Show your working clearly on your paper.
