Subtraction with more than 4 digits Foundation

In this worksheet, children subtract whole numbers with more than four digits, including using formal written methods (columnar subtraction).

Place value chart and place value counters can be used for support. It is useful when performing calculations that require an exchange. Squared paper and labelled columns will support children in placing the digits in the correct columns.

Children experience both questions and answers where zero appears in columns as a placeholder.

For a support ask, “Which number goes at the top when using the column method?”

“Does it matter if the numbers have different numbers of digits?”

“How do you know which digits to “line up” in the calculation?”

“How do you know if the calculation is a subtraction?”
