Divide a 2-digit by a 1-digit number using partitioning and representations (no remainders)
Lesson details
Learning outcome
I can divide a 2-digit by a 1-digit number using partitioning and representations (no remainders).
Key learning points
- Skip counting in steps of the divisor can be used to divide 2-digit numbers.
- Dividends can be partitioned into multiples of the divisor to divide efficiently.
- Unitising language is used to describe the process of division.
Keywords
Dividend - The amount that you want to divide up.
Divisor - The number you divide by.
Partial quotient - Part of an answer to a division equation.
Partition - Splitting an object or value into smaller parts.
Quotient - The result after division has taken place.
Common misconception
Some children may continue to share one by one when dividing.
Encourage children to skip count in the divisor and remind children that it is an efficient way of dividing.
Teacher tip
Model clearly using language of unitisation, ask children to join in when modelling language. Use concrete resources to exemplify structure of division. Remind children that partitioning the dividend gives us partial quotients.
