Identifying remainders is an important skill when dividing. It’s really important that we can see the number and understand where the remainder comes from. Throughout this week we will be looking at division by 2, 3, 4, 5 and 6.
We will be using concrete materials, drawing pictures, counting and many more strategies in order to reinforce this skill.
The rules below helps us to recognise if a number can divide equally. At the moment we are working on identifying numbers within 100 which divide equally by 2, 3, 4, 5 and 6. This will help us identify when we should have a remainder.
To practise this at home.
Choose any number and encourage pupils to consider if it is even, adds up to 3, ends in 0 or 5. If not then it will have a remainder when divided by 2, 3 and 5.
For example
255
This number will divide equally by 3 because 2+5+5 = 12. It end in an 5 so it will divide equally by 5. However as it is an odd number it will have a remainder when divided by 2.
