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