Whole numbers

1.1 Counting and representing bigger numbers

Look at the next page.

There are ten thousand stripes on the next page. Ten thousand is written like this in number symbols: 10 000

On two pages like the next page, there will be twenty thousand stripes altogether. Twenty thousand is written like this in number symbols: 20 000

On nine pages like the next page, there will be ninety thousand stripes altogether. Ninety thousand is written like this in number symbols: 90 000

On ten pages like the next page, there will be a hundred thousand stripes altogether. Hundred thousand is written like this in number symbols: 100 000

1. Write the number symbols for each of the following numbers. (a) forty thousand (b) seventy thousand (c) one hundred and twenty thousand (d) two hundred thousand (e) two hundred and sixty thousand (f) four hundred thousand

2. Count and write the number symbols as you go along. (a) Count in ten thousands from 20 000 up to 180 000. (b) Count in ten thousands from 200 000 up to 400 000.

3. One metre is 1 000 millimetres. Write your answers to the questions in words and in symbols. This means you must write the number names and the number symbols. (a) How many millimetres are equal to 3 metres? (b) How many millimetres are equal to 30 metres? (c) How many millimetres are equal to 300 metres? (d) How many millimetres are equal to 280 metres? (e) How many millimetres are equal to 720 metres?

The number five hundred and sixty-seven thousand three hundred and twenty-eight can be broken down into the following place value parts:

500000 60000 7000 300 20 8

Imagine that the place value parts are written on strips of cardboard or paper.

The strips can then be put on top of each other to show what the number symbol looks like. The zeros of the bigger place value parts are hidden in the number symbol.

500000 60000 7000 300 20 8
