Mathematics - Term 2 - Week 10

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

Let's look at the number 56. The '5' is in the tens place, which means it represents 50. The '6' is in the ones place, representing 6. So, we can say that 56 is made up of 50 (from the '5') and 6 (from the '6'). We can write this as: 50 + 6 = 56.

Now, let's practice identifying place values together. I will say a two-digit number, and you will tell me the value of each digit. For example, if I say 72, what is the value of the '7'? (Students respond: 70). And what is the value of the '2'? (Students respond: 2). Great job! Let's try a few more numbers together.

Now it's your turn! Complete the worksheet where you will write the place value of each digit in the given two-digit numbers. For example, for the number 41, write down the value of '4' and '1'. After you finish, we will review the answers together.
