Road Safety
Unit C – Handling Data
•Answer a set of related questions by collecting, selecting and organising
relevant data (Year 5)
•Draw conclusions using ICT to present features and identify further
questions to ask (Year 5)
•Construct frequency tables, pictograms and bar and line graphs to
represent the frequencies of events and changes over time (Year 5)
•Solve problems by collecting, selecting, processing, presenting and
interpreting data, using ICT where appropriate, draw conclusions and
identify further questions to ask (Year 6)
•Construct and interpret frequency tables, bar charts with grouped
discrete data and line graphs; interpret pie charts (Year 6)
•Find and interpret mode of a set of data (Year 5)
•Describe and interpret results and solutions to problems using the
mode, mean, median and range (Year 6)

1975 - 1976?
2. What percentage of men passed their driving tests
between 1985 – 1986??
3. How many more men than women passed their driving
tests in 2002?
4. Estimate how many men passed their driving tests in
the period shown altogether.
5. What might the data look like for 2006? Explain why
you think this.

Graphical Stories
The water in the kettle takes 2
minutes to reach boiling point.
It boils for another minute
before it’s taken off the heat
and the water cools down.
Lewis walks to the start of the
race and then sprints for the
next 100 metres after which he
sits down and recovers.
David climbs up to the top of
the slide. He jumps onto the
slide, slides down and then
jumps up and off at the end.

Line Graph Questions
1. At what angle was the ramp when the toy car
travelled 15cm?
2. How far did the toy car travel when the ramp was
at 30°?
3. At what angle was the ramp when the toy car
travelled 10cm?
4. When the ramp was at 55° how far did the toy car
travel?
5. What do you think will happen if the ramp is set at
90°?
