Using equivalence to calculate

Spine 2: Multiplication and Division – Topic 2.18

Introduction

Develop efficiency in calculation by using equivalence, through adjusting the factors (in multiplication) and the dividend and divisor (in division).

Teaching points

  • Teaching point 1: For multiplication, if there is a multiplicative increase to one factor and a corresponding decrease to the other factor, the product stays the same.
     
  • Teaching point 2: For division, if there is a multiplicative change to the dividend and a corresponding change to the divisor, the quotient stays the same.
