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 means 30, while the '4' is in the ones place and means 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, which means it represents 6. So, 56 can be broken down into 50 + 6. We can use blocks or drawings to visualize this: 5 blocks of ten and 6 single blocks.

Now, let's practice together. I will say a two-digit number, and you will tell me the value of each digit. For example, if I say 72, you will say '7 is in the tens place and represents 70, and 2 is in the ones place and represents 2.' Let's try with the number 45. What are the values of each digit?

Now it's your turn! Solve the following problems on your own. Write the number, identify the tens and ones, and show your work. 1. What is the place value of the digits in the number 82? 2. Break down the number 39 into tens and ones. 3. Write the number that has 4 tens and 3 ones.
