Key learning points
- If the dividend is a multiple of the divisor, there will be no remainder.
- If the remainder is greater than the divisor, another equal group can be made.
- If the remainder is known, the possibilities for a missing divisor can be found.
- If the divisor is known, the possibilities for a missing remainder can be found.
- This knowledge can help when solving missing number equations.
Keywords
Dividend - The dividend is the whole amount to be divided into groups or divided into equal parts. It is what we are dividing.
Divisor - The divisor is the number in each group or the number of equal parts that the whole is divided into or between. It is what we are dividing by.
Remainder - A remainder is the amount left over after division when the dividend does not divide exactly by the divisor.
Common misconception
Children may either choose to use a multiple higher than the dividend, e.g. 53 ÷ 9 = , or choose a multiple that is too low, e.g. 57 ÷ 8 = , which results in a remainder greater than the divisor.
When solving equations, refer back to the largest multiple that is less than or equal to the dividend and use number lines to allow children to visualise this.
