Mathematics - Term 4 - Week 6

Place value is the value of where a digit is in a number. In a two-digit number, the first digit represents the 'tens' place, and the second digit represents the 'ones' place. For example, in the number 34, the '3' is in the tens place and represents 30, while the '4' is in the ones place and represents 4. Together, they make 34.

Let's take the number 56. We can break it down into its place values. The '5' is in the tens place, which means it represents 50, and the '6' is in the ones place, which means it represents 6. So, 56 can be expressed as 50 + 6. This helps us understand how much each digit contributes to the overall number.

Now, let's practice identifying place values together. I will write a number on the board: 72. Can anyone tell me what the place value of '7' is? Yes, it is in the tens place, so it represents 70. And what about '2'? Correct, it is in the ones place, representing 2. Let's do another one: 45. What are the place values here?

Now it's your turn! Complete the worksheet where you will identify the place values of different two-digit numbers. For example, for the number 81, write down what the '8' and '1' represent. Make sure to show your working by breaking down each number into tens and ones.
