Mathematics - Term 3 - Week 8

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 256. We can break it down into its place values: 2 in the hundreds place (200), 5 in the tens place (50), and 6 in the ones place (6). So, 256 can be expressed as 200 + 50 + 6. This breakdown helps us understand how much each digit contributes to the overall number.

Now, let's practice together! Look at the number 482. What is the place value of the digit 8? It is in the tens place, so it represents 80. What about the digit 4? It is in the hundreds place, representing 400. Finally, the digit 2 is in the ones place, representing 2. Let's write these values down together: 400 + 80 + 2.

Now it's your turn! Solve the following problems on your own. 1. What is the place value of the digit 7 in the number 573? 2. Break down the number 631 into its place values. Write your answers clearly and show your working.
