Identify when there will be a remainder

I can use knowledge of times tables and divisibility rules to identify when there will be a remainder.

Lesson details

Key learning points

  1. If the dividend is a multiple of the divisor, there will be no remainder.
  2. If the dividend is not a multiple of the divisor, there will be a remainder.
  3. Times table knowledge can help to identify if there will be a remainder.
  4. The rules of divisibility can help to identify if there will be a remainder.

Common misconception

Children may work inefficiently, e.g. they may find the digit sum of 27 to find if it is a multiple of 6, instead of first reasoning that it cannot be because it is an odd number.

Encourage children to consider what they know about a number first (e.g. all even numbers have even multiples) before applying other parts of rules so that they work in the most efficient way. Display models of these to enable recall of them.

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.

Before solving a division problem, encourage children to consider the numbers involved. E.g. whether the dividend is a multiple of the divisor; whether they can use knowledge of times tables for numbers that lie within them and whether they can apply rules of divisibility for larger numbers.
