teacher’s Highlight that both pictographs and bar graphs are different ways of representing data in a more organised and
tip comprehensive way. While a bar graph is useful for showing large data sets and drawing comparisons between
numbers, a pictograph is ideal for presenting small numbers in a simple way that is easy to read at a glance.
