Lesson details

Key learning points

1. Negative data values can be recorded by extending the axes beyond zero

Common misconception

Inaccuracy when reading horizontally from the top of a bar to the y axis on a bar chart.

Model and encourage the use of rulers to follow a straight horizontal line from the top of a bar to the y axis.

Keywords

• Axis / axes - The x and y lines that cross at right angles to make a graph or grid.

Pupils who have completed the tasks can be asked to find other data from the bar chart beyond the questions asked. This could take the form of questions for a partner.
