equivalent fractions

31 Dec 2014

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

first

Students identify that of the diagram is shaded blue.

second

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

third

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.
