Subtract 4-digit numbers using column subtraction
Lesson details
Learning outcome
I can subtract two 4-digit numbers using column subtraction, regrouping hundreds, tens and ones.
Key learning points
- Column subtraction can be used to subtract 4-digit numbers.
- Work from the ones column on the right so that regrouping can be represented.
- If the tens value of the subtrahend is greater than the tens value of the minuend, regroup 1 hundred as 10 tens.
- If the hundreds value of the subtrahend is greater than the hundreds of the minuend, regroup 1 thousand as 10 hundreds.
Keywords
Column subtraction - Column subtraction is a way of subtracting numbers by writing a number below another.
Regrouping - The process of unitising and exchanging between place values is known as regrouping.
Common misconception
Trying to subtract 3 from 2 for example without regrouping and seeing the difference as 1
Continually acknowledge the whole and the parts in each 'column' so that children know what we have and what is being subtracted.
Teacher tip
Base 10 is used to support visualisation of the first few examples, but once able to do this, children should be able to apply their learning of column subtraction with 3-digits to 4-digit calculations and this scaffold can be removed.
