Adding numbers with more than 4-digits Core

In this worksheet, children revisit the use of the column method
for addition and learn to apply this method to numbers with
more than four digits.
Place value counters and place value charts are used for a support.
These representations are particularly useful when performing
calculations that require an exchange. Children may find it
easier to work with squared paper and labelled columns as this
will support them in placing the digits in the correct columns,
especially with figures containing different numbers of digits.
