1.07 Partition larger numbers

Lesson

Are you ready?

Before we look at breaking up $6$6 or 7 digit numbers, check if you remember how it worked with smaller numbers. 

Fill in the box with the missing number.

  1. $2592=2000+\editable{}$2592=2000+

Vocabulary:
  • Another word that we can use to describe the ones place is 'units'.

Let's see how we can partition a number in the hundreds of thousands, and then how to partition a number slightly differently, to solve a division problem.

Apply

Question 1

Fill in the boxes with the missing numbers.

  1. $4888333=\editable{}+800000+80000+\editable{}+300+30+\editable{}$4888333=+800000+80000++300+30+

Question 2

For the following questions use the digits $9$9, $8$8, $8$8, $3$3, $5$5 and $1$1.

  1. Make the largest number possible.

  2. Make the second largest number possible.

 

Remember!

Partitioning by place value is really useful, but sometimes breaking up a number into other parts is a great way to help solve problems.

Outcomes

3.NBT.A.4

Read and write multi-digit whole numbers (less than or equal to 100,000) using standard form, word form, and expanded form (e.g., 23,456 can be written as 20,000 + 3,000 + 400 + 50 + 6).
