Lesson details
Key learning points
- Multiples of 3 have a digit sum of a multiple of 3 and multiples of 6 are even multiples of 3
- If you can halve a number twice and get a whole number then the original number is a multiple of 4
- If you can halve a multiple of 4 and get a whole number then the original number is a multiple of 8
Keywords
Divisible - Divisibility is a number’s ability to be exactly divided by another number, leaving no remainder.
Divisibility rules - Divisibility rules let you test if one number is divisible by another, without having to do too much calculation.
Common misconception
Pupils may confuse the divisibility rules or apply them incorrectly.
Display the rules so pupils can be reminded of them. Clarify each rule with clear examples and practice problems (e.g., a number is divisible by 3 if the sum of its digits is divisible by 3).
