Powerpoint and print out of practice plotting time series table of values.
This powerpoint contains a set of key things to identify when interpreting time series graph and an activity to draw a graph.
Normally it takes learners/pupils a long time to draw axes and plot points but this variation of a Kagan activity works really well. All 4 learners in a group work on their own graph to start with. After 2 minutes they swap sheets with another member of their 4 and continue the work of another person. This swapping continues until they have 4 complete time series graphs. A great way for them to spot misconceptions and to learn from each other.
