A line graph is a graph where the points are connected by lines. It shows how something changes in value, usually over time.

A variable is something that changes and can also be measured.

The x-axis is the horizontal line on a graph which goes through zero.

The y-axis is the vertical line on a graph which goes through zero.

Interpret line graphs representing two variables in familiar contexts

Maths

Use understanding of angles, fractions and percentages to interpret pie charts

Use understanding of angles, fractions and percentages to construct pie charts

Construct line graphs representing two variables in familiar contexts

Interpret the scales used in graphs, including pie charts, to solve problems

In this unit pupils will interpret and construct pie charts and line graphs and use these to solve problems. They will read scales in graphing and measures contexts linking to fractions, angles, percentages and understanding proportional relationships In the future unit pupils will learn how to calculate the mean of a set of data and use the mean to make comparisons between two sets of information

In the prior unit pupils explained what percent meant and how to represent a percentage in different ways. They learned how to convert percentages to decimals and fractions and solved conversion problems. In this unit pupils will interpret and construct pie charts and line graphs. They will read scales  linked to fractions angles percentages and understanding proportional relationships.
