Task

Students work individually, using computers. They open the slideshow and observe how we can present data using percentage diagramspercentage diagramspercentage diagrams.

[Slideshow]

The teacher starts a conversation about legibility of information presented on the diagram.
Conclusions that should be drawn:

- A diagram should be titled.

- There should be a clear scale on the diagram.maf93b53eaae10b1a_1527752263647_0There should be a clear scale on the diagram.

- The quantities presented on the diagram should be described.maf93b53eaae10b1a_1527752256679_0The quantities presented on the diagram should be described.

The teacher divides the class into five groups and distributes worksheets where they find diagrams presented on the slideshow.

Task

Put necessary information on diagrams. Suggest a title and a description. Think about information that can be obtained from this diagram. Write exemplary questions and answer them.
