Next week the children will be learning about how to estimate volume of a shape and solving statistic questions.

Volume

The volume of a shape measures the 3-dimensional amount of space that it takes up. Volume is measured in **cubes**.

A cubic cm has sides of length 1cm. It has a volume of 1cm^{3} (1 cm cubed).

This cuboid contains 12 cubes. Each cube has a volume of 1cm^{3}. So the volume of this cuboid is 12cm^{3}

Statistics

Data means information. Graphs, charts and tables are used to represent this information and make it easier to understand. Bar charts are one way of showing the information from a frequency table. This bar chart represents the data from the table on the previous page:

The heights of the bars in this bar chart show **how many** of each bike were sold.
