A line graph is a graph where the points are connected by lines.

A pie chart is a circular graph where sectors represent different groups in proportion to each other.

A sector is a part, or ‘pie-slice’ part, of a pie chart.

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

Maths

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

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

Interpret line graphs representing two variables in familiar contexts

Construct line graphs representing two variables in familiar contexts

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.
