Mathematics - Term 1 - Week 2

Place value is the value of where a digit is in a number. For example, in the number 23, the '2' is in the tens place and represents 20, while the '3' is in the ones place and represents 3. Together, they make 23. Understanding place value helps us to read, write, and compare numbers.

Let's take the number 45. The '4' is in the tens place, which means it represents 40. The '5' is in the ones place, which means it represents 5. So, we can say that 45 is made up of 40 (4 tens) and 5 (5 ones). We can also use blocks or drawings to show this: 4 groups of ten blocks and 5 single blocks.

Now, let's practice together! I will say a number, and you will tell me the value of each digit. For example, if I say 32, what is the value of the '3'? (Students respond: 30). And what is the value of the '2'? (Students respond: 2). Great job! Let's try a few more numbers together: 51, 76, and 84.

Now it's your turn! Complete the worksheets where you will be given different two-digit numbers. For each number, write down the value of each digit and draw a picture using blocks to represent the number. Remember to show your working clearly. After you finish, we will review your answers together.
