5.04 Partition numbers with decimals

Lesson

Are you ready?

We can partition decimals in the same way we partitioned whole numbers. Let's try this problem to practice. 

We have written a number in the number expander.

  1. What is the value of the tens?

  2. What is the value of the hundreds?

Learn

In this video we explore how to partition decimals into multiple parts which match their place value representation. 

Vocabulary:

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

Apply

Fill in the box with the missing number.

  1. $0.358=0.3+0.05+\editable{}$0.358=0.3+0.05+

Remember!

Number expanders help us to position the number in the correct place value column which can then help us write the number using partitioning.
