Use Place Value To Order 3 And 4 Digit Numbers

Hi, my name is Ben. And in this video we're going to be looking at how to use place value to order three and four digit numbers. Now we've already looked at place value on previous videos and the importance of it. So Here we've got four numbers. We've got 597, 593, 7182 and 8249. Now we want to order these numbers in descending order. That's going from the largest to the smallest. So the first thing we have to do is we look into the thousands column because that's where the largest number is. And we can see that we have two three digit numbers and two four digit numbers. So here we have a number beginning with seven and a number beginning with eight. So this number here, eight is larger than seven, so that's the larger value. So that's the largest number, 8,249. And then the second largest number is the one with the seven in the thousands column because the seven represents seven thousands. So that's 7182. Now we move on to the two three digit numbers. Now we have no value in the thousands column. So we have to move to the next column to the right. In this case it's the hundreds column. And here we have 500 and 500. They're both equal. So now we have to apply the same rule and move to the right into the next column, which is the tens. Here we have nine tens and nine tens. So we have to move again to the right and we have seven ones and three ones and seven ones has a high value. So the next number is 597 and then finally 593. So here you can see the four numbers in descending order from the largest to the smallest, using the place value column to really understand the value of each digit. Now, an idea that you can do with your children is to look at numbers that have got the same digits but in a different order. 654, 456, etc. And see if they can play around with those numbers and order them from largest to smallest, from smallest to largest, which will be ascending. And that's how we can use place value to order three and four digit numbers.
