      Checking understanding of pictograms and bar charts

      I can interpret both pictograms and bar charts.

      Lesson details

      Key learning points

      1. Pictograms represent data through images.
      2. Bar charts represent data using the heights of bars.
      3. A key and/or labelled axes are important for interpreting the representation.

      Keywords

      • Frequency - The number of times an event occurs; or the number of individuals (people, animals etc.) with some specific property.

      Common misconception

      Pupils may forget the key with a pictogram or mislabel the vertical scale for bar charts.

      By asking the pupils how they know there are 'x things', to highlight the need for the key.

      If your pupils have shown any need for further work on pictograms and/or bar charts then you may wish to use lesson 2 and 3 of this unit. Real data collected within class is always nice to use when creating their own pictograms and bar charts.
