Coral and Sandy want to go on holiday to either Penzance or Bournemouth. They are using a number of line graphs to work out when and where to go.

Discussion points for teachers
1.Estimate the temperature in Penzance and Bournemouth in May.
Discuss how the line and markers that are already in place can be used to estimate.
Penzance 17oC, Bournemouth 16oC
2.Where can they go and in which month?
Discuss how to use the parameters set to narrow down the available answers.
Bournemouth in June or Penzance in July.
3.Create a scenario based on the data plotted on the graph.
Discuss a story that might use the numbers involved and the comparison between two data sets. This question is open-ended for children to explore.
Various answers, for example: Two towns are comparing visitor numbers over the summer. In May, town 1 had more visitors than town 2. Both increased to their highest number of visitors in June, which was 1,000. Visitor numbers for both towns fell as the summer continued, possibly due to the wet English summers, although town 1 saw a sharp increase in August. By September, both towns had less than 400 visitors.
4.Who do you agree with?
Discuss how to extract the data from the table and the calculation required to answer the question and find the difference.
Coral is right because from Saturday to Tuesday at Hotel Riviera de Cornwall there are 380 visitors, whilst there are 420 visitors at both hotels from Wednesday to Saturday.
5.When are the best times for her to go?
Discuss the key information – the higher the number, the higher the tide – and how this can be used to find suitable low times. Discuss information provided that is too open ended to use. ‘She doesn’t like walking’ but we don’t know how far she will walk. Discuss feasible answers – is she likely to go shell picking in the dark?
09:00 – 15:00, 00:00 – 03:00, 21:00 – 00:00 although a discussion on feasible answers is possible.
Which hotel and which days would be the quietest time for the two to visit, if you could pick any four consecutive days? Why do tide graphs exist?
