Place Value and Ordering Numbers

In Maths we have been learning about how to order numbers up to ten thousand. Our task was to write down a number between 1 and 10,000. We then worked in groups of 8 and we had to order our numbers from greatest to smallest. We then had to explain how we decided which numbers go in which order. Check out some of our videos to see our explanations.

As you can see the place value of each number played an important part in deciding the orders of the numbers. In our number system, the value of a digit depends on its place, or position in the number. Each place has a value of 10 times the place to its right.

We then played a game using 6 x sided dice and 2 players. Each player rolled the dice and then used the numbers on the 4 dice to write the largest and smallest number possible. Many of us figured out the pattern that the whatever the largest number was, the smallest number was written in reverse. We had to do this 6 times each. As an extra challenge we then ordered our highest and lowest numbers into descending order.

We also have been learning about Place Value.

Place – means the location of a digit in a number

Value – means how much the digit is worth.

We have been looking at numbers up to the millions.

We learnt that there are 4 main ways to show a number. These are:

Standard Form – writing the number using digits

Worded form – writing the number in words

Expanded Form – expanding the number to represent that value of each digit

Base 10 Form – showing the number visually using the base 10 blocks.

As a class we have been practising how to represent a number each of the four ways. Check out some of our work below.

We also each had a turn using the Base 10 blocks. We had 5 dice and we rolled each one and made the largest number or the smallest number possible using these numbers. We then had to use the blocks to show the number as a Base 10.

Can you explain how to order large numbers into largest and smallest?

What do you find challenging with ordering large numbers and why?

Can you think of a time in everyday life where you would need to order numbers in ascending or descending order?

  1. Dear mrs Baldwin,
    You have to look at the first number and if its the same look at the second number if thats the same look at the next number and so on.

    I don’t find it hard but the hardest bit is the middle number because you have to count in between the largest and smallest numbers.

    For maths homework because that is our topic.

  2. Dear Mrs Baldwin,
    Well ordering large numbers and small numbers is ordering the highest number to the lowest number so you have to check all the digits so the number with all the highest digits goes first.

    I sometimes don’t find it hard but the hardest part is probably the middle number because its one of the hardest numbers to use for going backwards but its good for using zeros.

    For maths homework.
