Lesson details
Key learning points
- If the dividend is multiplied by 100 then the quotient will be one hundred times the size.
- The dividend is equivalent to the product in the inverse calculation.
- 18 divided by 6 is equal to 3 so 1,800 divided by 6 is equal to 300 or 18 hundreds divided by 6 is equal to 3 hundreds.
Keywords
Dividend - The dividend is the number being divided.

Common misconception
Because multiplication is commutative and division isn't, finding related division facts can be tricky. For example, 15 ÷ 3 = 5 is related to 3 × 5 = 15 despite the factor's positions swapping.
Get children to write 2 related multiplication facts from a division fact. For example, 3 × 5 = 15 and 5 × 3 = 15 are related to 15 ÷ 3
