Lesson details
Key learning points
- Partitioning the dividend into hundreds, tens and ones helps when dividing a 3-digit by a 1-digit number.
- Use times tables and unitising to divide the hundreds, tens and ones by the divisor.
- Place value resources can represent the division.
Keywords
Dividend - The dividend is the amount that you want to divide.
Divisor - A divisor is the number we divide by.
Partial quotient - A partial quotient is seen when the dividend is partitioned.
Partition - Partition means splitting an object or value down into smaller parts.
Quotient - A quotient is the result after division has taken place.
