## Lesson details

### Key learning points

- Partitioning the dividend into tens and ones helps when dividing a 2-digit by a 1-digit number.
- If the dividend is not a multiple of the divisor, there will be a remainder.
- If the remainder is a number of tens, you can exchange the tens for ones and continue to divide.
- If the number of ones is not a multiple of the divisor, there will be a remainder as part of the quotient.

### Common misconception

Pupils may forget to record the remainder.

Remind children that if the ones are not divisible there will be a remainder and that this is expressed as 'r'.

### Keywords

Remainder - A remainder is an amount left over after division.

Regroup / regrouping - The process of unitising and exchanging between place values is known as regrouping.
