1.01 Read and write numbers
Are you ready?
Before continuing on in this lesson, check that you know how to read and write 5 digit numbers. Remember we use a zero place holder when our number has no digits in one or more places.
Do you remember the names of the place value columns?
Read and write numbers to millions
In this video, we use a place value table to show how we can represent numbers in the hundreds of thousands. Expanded notation, or partitioning, is also used to show how we can break up large numbers by place value components.
Exploration
Use the applet to write the numerals of the number using the sliders.
The sliders serve as the place value columns where we can write the digits of the given numeral.
Examples
Example 1
Fill in the digits in the table to express the number five million, twenty six thousand and eighty five.
| Millions | Hundreds of Thousands | Tens of Thousands | Thousands | Hundreds | Tens | Ones |
|---|---|---|---|---|---|---|
| \quad | \quad | \quad | \quad | \quad | \quad | \quad |
Example 2
How do we write 7\,200\,009 in words?
In 6 digit numbers, the largest place value represents the hundreds of thousands column. 100\,000 is read as "one hundred thousand".
