Problem solving with graphical representations of data
Lesson details
Learning outcome
I can use my understanding of various graphical representations to solve problems.
Key learning points
- Data can be presented in various formats.
- A fuller picture can be obtained when considering more data.
- Multiple representations may be unnecessary.
Keywords
Bar chart - A bar chart (bar graph) is a graph consisting of bars visually representing the frequency of objects or groups.
Pie chart - A pie chart (pie graph) is a circular graph where sectors represent different groups proportionally.
Scatter graph - A scatter graph is a visual representation for bivariate data. It can help determine the nature of the relationship between the variables.
Common misconception
Pupils may think that data is only presented using the types of graphs that they learn in school.
Data can presented visually in anyway that helps people to understand it. Explore other types of graphs and infographics used in the media.
Teacher tip
More large data sets can be found online. Pupils can be encouraged to explore these. The MEI CODAP project allows pupils to analyse different large data sets.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
