Mathematics - Term 1 - Week 2

Place value is the value of a digit depending on its position in a number. For example, in the number 34, the digit 3 is in the tens place, which means it represents 30, while the digit 4 is in the ones place, representing 4. Understanding place value helps us read, write, and compare numbers accurately.

Let's take the number 57. The digit 5 is in the tens place, so it represents 50. The digit 7 is in the ones place, so it represents 7. Therefore, 57 can be broken down into 50 + 7. When we write it in expanded form, it looks like this: 5 tens + 7 ones.

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 82, what is the value of the digit 8? (Students respond: 80). What about the digit 2? (Students respond: 2). Great job! Let's try a few more numbers: 46, 91, and 73.

Now it's your turn to solve some problems on your own. Write the following numbers in expanded form: 24, 39, and 51. Then, for each number, identify the value of the tens and ones digits. Remember to show your working clearly!
