Multiplication with three factors and volume

Spine 2: Multiplication and Division – Topic 2.20

Introduction

Use multiplication to calculate the volume of cuboids and shapes comprised of several cuboids; use division to solve associated inverse problems. Use associativity and commutativity to solve abstract multiplication problems with three factors.

Teaching points

  • Teaching point 1: Volume is the amount of space that something occupies.
     
  • Teaching point 2: Volume is measured in cubic units, such as cubic centimetres (cm3) and cubic metres (m3).
     
  • Teaching point 3: The volume of a cuboid can be calculated by multiplying the length, width and height.
     
  • Teaching point 4: Both the commutative law and the associative law can be applied when multiplying three or more numbers.
     
  • Teaching point 5: The choice of which order to multiply in can be made according to the simplest calculation.
