Checking understanding of bar charts and pictograms

I can construct/interpret bar charts and pictograms.

Lesson details

Key learning points

  1. Certain data is suitable for a pictogram or bar chart.
  2. The shape of the graph can be estimated from the data.
  3. For larger data sets, technology can make constructing graphs quicker.

Common misconception

Pupils may miss the key in a pictogram, or the axes labels on a bar chart.

Pupils could be provided with a success criteria list, which they get in a habit of checking after constructing pictograms and bar charts.

Keywords

  • Bar chart - A bar chart (bar graph) is a graph consisting of bars visually representing the frequency of objects or groups.

  • Pictogram - A pictogram (pictograph) is a graph consisting of pictures to visually represent the frequency of objects or groups.

Discuss with pupils, data that could be collected and easily represented on a pictogram and data that would be less easy to represent on a pictogram.
