Construct and interpret graphs in real-world contexts.

e.g. distance-time, money conversion, temperature conversion

[see also Direct proportion, 5.02a, Inverse proporion, 5.02b]

Recognise and interpret graphs that illustrate direct and inverse proportion.[/i]

#7.04b

Understand the relationship between gradient and ratio.

Interpret straight line gradients as rates of change.

e.g. Gradient of a distance-time graph as a velocity.

Calculate or estimate gradients of graphs, and interpret in contexts such as distance-time graphs, velocity-time graphs and financial graphs.

Apply the concepts of average and instantaneous rate of change (gradients of chords or tangents) in numerical, algebraic and graphical contexts.

#7.04c

Calculate or estimate areas under graphs, and interpret in contexts such as distance-time graphs, velocity-time graphs and financial graphs.
