Securing constructing bar charts by hand
I can construct bar charts from data.
Lesson details
Key learning points
- Data presented as a list can be represented as a bar chart
- Data presented in a table can be represented as a bar chart
- The type of data determines how the bars should be drawn
Keywords
Frequency - The frequency is the number of times an event occurs; or the number of individuals (people, animals etc.) with some specific property.
Bar chart - A bar chart (bar graph) is a graph consisting of bars visually representing the frequency of objects or groups.
Data - Data are a collection of information.
Common misconception
Pupils may label the vertical axis with the frequency values rather than a scale.
Remind the pupils that the scale should go up in the same jumps. i.e. 0, 5, 10, 15 etc and have them check theirs.
If your pupils showed good understanding of bar charts from lesson 1 of this unit, then you may wish to skip this lesson.
