Educational software theory used:

Place Values With A 3 Unit Pole

Each digit in a number has a different unit value.

Similarly each pole also has a different unit value.

Numbers

The far right column of numbers is called the ‘Ones’ units. Each value in this column represents 1 item.

When we move to the next column, we call these units ‘Tens’. Each value in this column represents groups of 10.

As we move further to the left, the next column is called the ‘Hundreds’ units. Each value in this column represents groups of 100.

This pattern continues for each subsequent column and they are known as ‘Thousands’, ‘Ten Thousands’, ‘Hundred Thousands’, ‘Millions’ etc..

Unit Poles

Unit poles are made up the same way as our number patterns and have corresponding place values.

The far right pole is called the ‘Ones’ units. Each bead on this pole represents 1 item.

When we move to the next pole, we call these units ‘Tens’. Each bead on this pole represents groups of 10.

As we move further to the left, the pole is called the ‘Hundreds’ units. Each bead on this pole represents groups of 100.

Educational software Instruction :

1.  Adjust the Unit Poles to show the given number.

2.  Use the ‘Up’ and ‘Down’ buttons to change the number of beads on the poles.

3.  Click the ‘OK’ button when you have finished.
