A graph is a visual way of showing information. A Bar Graph uses bars of different lengths or heights to represent information.

An axis on a graph is a fixed measuring line that runs horizontally (left to right) and/or vertically from zero:

Using graphs to represent lengths and heights

Maths

In this unit pupils will continue to measure using appropriate tools and units progressing to using a wider range of measures including comparing and using mixed units In the future unit pupil will learn perimeter as the distance around the edge of a 2D shape They will learn perimeter is measured in units of length found by counting units and by calculating by adding the side lengths of a 2D shape

In the prior unit pupils chose, used and compared appropriate standard units to estimate and measure length/height, mass, temperature, capacity to the nearest appropriate unit. In this unit pupils will continue to measure using appropriate tools and units progressing to using a wider range of measures, including comparing and using mixed units.

Measuring length and recording in tables

A line on a bar graph that runs horizontally (left to right) from zero is known as {{ }}.

If we were to represent the data in this table in a bar graph, what maximum value would be needed for the numerical axis?

If we were to represent the data in this table in a bar graph, what should the numbers labelled on the axis increase in?

Look at the bar graph comparing the length of some objects.  Match the object to its length.

Look at the bar graph comparing the length of some objects.  Which object is the shortest?

Look at the bar graph comparing the length of some objects.  What is the difference in length between the longest and shortest object?

Match the multiples with their times-table.

How tall is this mouse? Tick all the options that apply.

The estimated length that Izzy can kick a football.

The actual length that Izzy can kick a football.

The actual length that Andeep can kick a football.

The estimate length that Jacob can kick a football.

Look at this table showing estimated and actual lengths that children can kick a football.  What does the 35 m represent?

Match the letters to their appropriate number on this number line.
