Main Activity

The slides explore different and novel ways data can be visualised.

Visualisation is part of the analysis step of PPDAC the data problem solving framework.

Learners should complete two tasks:

  • Slide 3: identify interesting data in their tally chart from lesson 2.
  • Slide 16: Create your own visualisation

Students should draw one of the items for their theme in the corner of the box, they should then make one change and draw a series of that change (they will need this for choosing which change should represent each questions – if they have five answers and can only think of two changes they will not be able to use that change) size, shape, colour, thickness, angle etc. and repeat this through as many changes as they can.


  • 0-10 minutes: introduce the changes using leaves and lines examples
  • 10- 35 minutes: Three themes expanded on design sheet to show the changes that could form the key (8 min a theme)
  • 35-40 minutes: The layout how to match the topic to the positioning in the final visualisation
  • 40-50 minutes: sketch layouts for two of the three themes.
