Higher Year 4 Subtraction with one exchange with answers
These are PDF files that you can print off at home.
Children work out 4-digit subtraction word problems and correct the mistakes and explain the exchange. Reasoning is included in each question.
Each sheet comes with a well explained answer sheet.
Use this question to challenge your child.
How can you subtract two numbers if one of them has fewer digits than the other?
Children may not line up the digits in the place value columns correctly, especially when the numbers have different numbers of digits.
Children may find the difference between the two digits in a column instead of subtracting the second digit from the first in order to avoid an exchange, for example 1 – 3 becomes 3 – 1
