Graphs
Line graphs and global graphs: increasing, decreasing or constant. Read one part at a time and tap “I know this”. Then test yourself in the quiz.

Reading graphs
- Read the title and the axis labels first.
- A line graph shows how something changes over time.
- Steep line = fast change; flat line = no change.
Global graphs
A global graph has no exact numbers; it shows the trend: increasing, decreasing or constant. E.g. a bath filling (up), staying full (flat) and draining (down).
- Linear: the graph is a straight line (it changes at a steady rate). Non-linear: the graph is curved (the rate changes).
- Draw a global graph from a story: read each part in order and decide: increasing, decreasing or constant? A car speeds up, drives at a steady speed, then stops: the speed goes up, stays flat, then drops to 0.
Remember this and test yourself
- Read the title and axes first.
- A line graph shows change over time.
- Steep = fast; flat = no change.
- A global graph shows the trend.
- Linear = straight line; non-linear = curved line.
Write these points in your book. Read them again the night before the test.
Up = increasing, down = decreasing, flat = constant.
