Students learn to plot a time series and recognise trends over time.

As learning progresses, students consider seasonal changes and hypothesise about their occurrence.

**Differentiated Learning Objectives**

- All students should be able to recognise and describe a trend over time from a time series.
- Most students should be able to plot a time series and trend line to describe upward, downwards or level trends.
- Some students should be able to recognise and describe seasonal variations from a time series.
