1.02 Partition 5 digit numbers

Lesson

Are you ready?

Can you partition numbers up to the thousands ($4$4 digits)?

We have written the number $2040$2040 in a number expander.

Fill in the boxes to make the sentences correct.

  1. This number is made up of $\editable{}$ thousands and $4$4 tens.

  2. We can also break up $2040$2040 into hundreds and ones.

    This number is made up of $\editable{}$ hundreds and $40$40 ones.

Learn 

Let's see how to break up a $5$5 digit number, and then put it back together. We'll start with a $4$4 digit number to warm up.

Question 1

Complete in the number expander for $18522$18522.

  1. $18522$18522 $=$= $\editable{}$ ten thousands $\editable{}$ thousands $\editable{}$ hundreds $2$2 tens $2$2 ones
  2. Write $18522$18522 as a number sentence.
    $\editable{}+\editable{}+\editable{}+20+2$+++20+2

Question 2

Write the following as a single number: $60000+1000+80$60000+1000+80.

Remember!

Except for the far left digit of our number, every place must have a number in it. If we don't have any of a place, we must put a zero in that place. The number twenty eight thousand and forty nine has no hundreds, so we would write it like this $28049$28049.
