# Students’ Notes for “Modeling Numbers: 6 digits”

The Ministry is migrating nzmaths content to Tāhurangi.
Relevant and up-to-date teaching resources are being moved to Tāhūrangi (tahurangi.education.govt.nz).
When all identified resources have been successfully moved, this website will close. We expect this to be in June 2024.
e-ako maths, e-ako Pāngarau, and e-ako PLD 360 will continue to be available.

This Learning Object helps you see how numbers up to 999 999 can be shown using equipment. The equipment is called place value equipment.

You can make your own number by clicking the up and down arrows or by using the arrows and numbers on the keyboard. As you make your number the equipment underneath will show it. The colour of the equipment in each column changes for the 6th cube, rod or block. This will help you quickly recognise the numbers between 6 and 9.

There is a magnifying glass button  that allows you to zoom in and out to see the columns.
Below the place value equipment the number is shown in words.
By clicking the left and right arrows   you can change the representation from words, to a place value house, standard form, or two 3-bar abacuses.

The ones, tens, and hundreds columns are in blue and the thousands, ten thousands, and hundred thousands are in red. The colour of the representations matches the colour of the place value columns.
When the number is represented using words you can click on the speaker icon  to hear the number spoken.
