Place
Value
- Place value is the basis of our entire number system. A place
value system is one in which the position of a digit in a number
determines its value.
- In the standard system, called base ten, each place represents ten times the value of the
place to its right.
- making groups of ten of the smaller unit and combining them to make
a new unit.

- Why do we need to teach place
value
- Because it forms
the basis of our
number system
- So children understand that the
same digit can be used to
represent different amounts.
- So children can work out the value of
each digit depending on its position
- So children can express
amounts using digits and
communicate with numbers.
- Because it forms
the basis of our
number system
- Why can place value be
challenging to teach?
