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.
Why can place value be
challenging to teach?
