A number can be made in the Learning Object by either clicking the arrows above and below each digit or using the arrows and numbers on the keyboard. As the number is made the place value equipment below the number changes to match. The user will notice the colour change for the 6th cube, rod or block. This makes it easier to quickly recognise numbers between 6 and 9. The colour of the words under the place value equipment matches the colour of the columns.
Clicking the magnifying glass icon allows the user to zoom in and out to see the place value columns.
