Interpret the scales used in graphs, including pie charts, to solve problems
I can solve problems using line graphs and pie charts.
Lesson details
Key learning points
- A pie chart represents parts of a whole.
- A line graph represents the relationship between two variables.
- Place value helps you to interpret partially marked scales and axes.
Keywords
Line graph - A line graph is a graph where the points are connected by lines.
Pie chart - A pie chart is a circular graph where sectors represent different groups in proportion to each other.
Sector - A sector is a part, or ‘pie-slice’ part, of a pie chart.
Common misconception
Pupils may make errors interpreting information from pie charts, especially with making links between angles, fractions, percentages and working out an answer to a question.
Display 'benchmarks' in the classroom, showing a pie chart with labelled sectors (e.g. showing that 10% is equal to one tenth or 36° of the chart; 25% is equal to one quarter or 90°).
Pupils need to have some familiarity with both line graphs and pie charts before this session. Give the pupils a chance to talk about the graphs too, making observations and asking questions (e.g. 'Why wasn't Izzy running here?' or 'The pie chart shows that Jacob scored the most points.')
