Having read a superb post about the Singapore Bar Model from William Emeny I thought I would share these diagrams for introducing equivalent fractions:

With each square now shown in two pieces, they can then see that is shaded and that this is equivalent to .


Once they are happy with the second step then there isn’t much of a leap to showing that .

Whilst these diagrams are given in a slightly different format to the bar model, the idea is similar.


Here is a small presentation that may be useful.
