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.
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.
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'.
