Resource of the Week: Subtraction of money

The standard written method of subtraction is usually used when adding amounts of money, but it can prove quite tricky as it involves decimals. It is important to lay the question out in the standard way, even if it is shown horizontally or just as a written problem and most importantly, to keep the decimal points in a line. if using squared paper it is best to puit the decimal point on the line rather than in a square.

Watch out when there is a zero on the top line as many children go for the easy option and say ‘nought take away 3 is 3’ rather than going through the carrying process.

This is just one of our series on subtracting money.
