Lesson details

Key learning points

  1. If the dividend is multiplied by 100 then the quotient will be one hundred times the size.
  2. The dividend is equivalent to the product in the inverse calculation.
  3. 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.

  • Divisor - The divisor is the number we are dividing by.

  • Quotient - The quotient is the result after division has taken place. It is the whole number part.

  • Scaling - Scaling is when a given quantity is made ___ times the size.

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
