Olympic Records
Why do this problem?
This problem gives students the opportunity to make sense of graphical data and challenges them to apply their own knowledge about athletics to explain and interpret key features of the graphs.
Possible approach
Arrange the class in groups of three or four, and give each group the ten graphs.
While they are working, circulate and listen to their reasoning. If some groups are stuck, here are some useful prompts:
- What can you deduce about the event if the record increases over time?
- What about events where the record decreases over time?
After they have had sufficient time to consider the graphs, ask them to write down a list of what events they think each represents.
Possible support
You may wish to hand out this list of the events and ask students to work out which belongs with each of the ten graphs.
Alternatively, this card sort activity contains the ten graphs and the events on cards for students to match up.
Possible extension
Ask students to carry out some extra research in order to explain unusual features in the graphs, such as:
- Drastic changes
- Long gaps
- Absence of data in the early twentieth century
- Records that go both up and down
Students could create their own set of graphs and challenge the rest of the class to work out which Olympic athletics events they relate to.
