Year 4 Maths: Term 2 Week 1

This week we will look at Place Value and Expanded Notation.

Place Value

We will discuss place value and complete a worksheet individually.

If we can find a deck of cards we can play the Millionaire Place Value Game!

Expanded Notation

Expanded notation is a helpful way to rewrite numbers to show the place value of each digit.

There are two methods we can use to show numbers in expanded notation. An example:

Example Question:
Q. Write the number 4,981 using expanded notation.

Method 1: 4,000 + 900 + 80 + 1
Method 2: (4 x 1,000) + (9 x 100) + (8 x 10) + (1 x 1)
