I can present soil texture data using creative techniques.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Data made up of three parts can be shown on a triangular graph.
  2. Proportional shapes or symbols can be used to compare the size of data values.
  3. All forms of data presentation need to conform to particular standards and use conventions to make them readable.

Keywords

  • Proportional data - data that can be split up into constituent parts

  • Triangular graph - a graph with three axes used to display proportional data with three constituent parts

  • Proportional shape - a symbol on a map or in a graph that shows a value of data by the size at which it has been drawn

Common misconception

Proportional data can only be presented using a pie chart.

A pie chart is by far the most common method that geographers use, but any shape can be split into proportional sections.

If you have access to a visualizer, use this to structure and plot the points on a triangular graph in real time. This tricky skill is often easier to comprehend when it is modelled to students.
