Information about length and height from a table can be represented in a bar graph.
Information represented in a bar graph can be used to solve problems.

Mistakes may be made on comparison problems. E.g. how much further does one child jump than another?

When we compare, we are finding the difference. To find the difference, we need to subtract the smaller value from the larger value.

Graph - A graph is a visual way of showing information. A Bar Graph uses bars of different lengths or heights to represent information.
Axis - An axis on a graph is a fixed measuring line that runs horizontally (left to right) and/or vertically from zero:
