Dividing by a 2-digit divisor including using long division
I can divide by a 2-digit divisor including using long division.
Lesson details
Key learning points
- Different strategies can be used to solve division problems.
- Multiplication facts are really useful in solving division problems.
- Known facts and place value can help to estimate the answer to a long division.
Keywords
Estimate - Estimate means to find a value that is close enough to the right answer, usually with some thought or calculation involved.
Long division - Long division is a method used for dividing large numbers by breaking the number down into smaller groups.
Remainder - A remainder is an amount left after a division.
Common misconception
Pupils may struggle to set out the long division algorithm correctly.
Use the modelling from the lesson to focus on this, especially when writing multiples of the divisor (e.g. 3 tens × 17 = 51 tens) and subtracting this from the dividend.
In this lesson, pupils will be dividing a 3-digit number by a 2-digit number outside of multiplication tables. However, they can use known or easily derived facts to help them (e.g. 2×, 4×, 5× and 10×). Discuss with pupils methods for multiplying by 30 or 40 (e.g. ×4 then ×10 or ×10 then ×4).
