Lesson details
Key learning points
- If you can halve a number then it must be a multiple of 2 and divisible by 2
- If you can halve a number and halve again then it must be a multiple 4 and divisible by 4
- If a number is divisible by 4 then it must be divisible by 2
Keywords
Divisibility - Divisibility is when division of a number results in another whole number.
Divisor - A divisor is a number that divides the integer exactly (no remainder).
Multiple - A multiple is the result of multiplying a number by another whole number.
Half / halve - A half is one of two equal parts of a whole.
Common misconception
Lack of fluency in 2s and 4s times tables and not understanding the divisibility rules or the problems.
To clearly model highlighting key words of worded problems to understand the problem and the operation required for the calculation. Continue to use language stems such as 'If I know...' 'Then I know...,' to support mathematical thinking.
