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
