Views of mathematics
Mathematics is …
• an important subject
• nothing to do with real life
• a boys’ subject
• something you can either do or you can’t
• about learning rules
• about right and wrong answers

Key Stage 3 National Strategy
Points for discussion
Consider the definition of numeracy (handout 1.2)
• Are there any areas of mathematics useful to your
subject which you feel are not covered by the
definition?
• Which aspects of the definition are most relevant to
the work of your department?
• Identify the two most important aspects of
numeracy you require for each of the Years 7, 8
and 9.

Key Stage 3 National Strategy
A definition of numeracy 1
By Year 9, pupils should:
• have a sense of the size of a number and where it fits into
the number system
• recall mathematical facts confidently
• calculate accurately and efficiently, both mentally and with
pencil and paper, drawing on a range of calculation
strategies
• use proportional reasoning to simplify and solve problems
• use calculators and other ICT resources appropriately and
efficiently to solve mathematical problems, and select from
the display the number of figures appropriate to the
context of a calculation

Key Stage 3 National Strategy
A definition of numeracy 2
By Year 9, pupils should:
• use simple formulae and substitute numbers in the
• measure and estimate measurements, choosing suitable
units, and reading numbers correctly from a range of
meters, dials and scale
• calculate simple perimeters, areas and volumes,
recognising the degree of accuracy that can be achieve
• understand and use measures of time and speed, and rates
such as £ per hour or miles per litre
• draw plane figures to given specifications and appreciate
the concept of scale in geometrical drawings and maps

Key Stage 3 National Strategy
A definition of numeracy 3
By Year 9, pupils should:
• understand the difference between the mean, median and
mode and the purpose for which each is used
• collect data, discrete and continuous, and draw, interpret
and predict from graphs, diagrams, charts and tables
• have some understanding of the measurement of
probability and risk
• explain methods and justify reasoning and conclusions,
using correct mathematical terms
• judge the reasonableness of solutions and check them
when necessary
• give results to a degree of accuracy appropriate to the
context

Priorities for cross-curricular numeracy
• To improve accuracy, particularly in
calculation, measurement and graphical work

Numeracy in Ofsted inspections
In relation to numeracy, inspectors should establish:
• whether there is clear understanding and consistent
practice among staff in the development of pupils’ mental
skills, written methods of calculation and use of calculators
• if pupils can identify and use an efficient strategy for the
calculations they need to do
• if pupils cope well with the mathematical demands made
in different subjects, or are held back through lack of
mathematical knowledge or poor basic skills in numeracy
• how well numeracy and, where appropriate, other
mathematical skills are taught, developed or practised in
other subjects
OHT 1.7

numeracy across the curriculum
• To introduce activities to develop oral
communication skills
• To discuss whether similar activities could be
used in other subjects when mathematical
skills are required

mathematics department, to benefit both
subjects?

Key Stage 3 National Strategy
Departmental policy on using
calculators

calculations without resorting to a calculator?
• Do we make it clear to pupils when and where we expect
them to use a calculator and when we expect them not to?
• How do the calculator skills we expect pupils to use line
up with those in the Framework for teaching mathematics?
• Are there opportunities in our scheme of work to teach or
reinforce identified calculator skills?
• Is our departmental policy consistent with the school
policy?

The handling data cycle
OHT 7.1
© Crown copyright 2001
Key Stage 3 National Strategy
Features of handling data in Key
Stage 3
• Basing work on purposeful enquiry, using
situations of interest and relevance to pupils and
making appropriate links to other subjects
• Placing an emphasis on making inferences from
data, drawing on a range of secondary sources
to ensure that samples are sufficiently large
• Using ICT as a powerful source of data, and as a
means of processing data and simulating
situations
OHT 7.2
© Crown copyright 2001
Key Stage 3 National Strategy
Handling data across the curriculum
• Are all the different stages of the handling data cycle
applicable to your subject?
• Have pupils handled data in any lessons that you have
taught recently?
• Which stages of the handling data cycle were pupils
engaged in?
• Which stages of the handling data cycle could pupils have
been engaged in?
• Which of the distinctive features of handling data were
present in the lesson(s)?
OHT 7.3

Key Stage 3 National Strategy
Common difficulties in handling
data 1 (i)
• Mean, median and mode are confused or used
inappropriately
For example, the mean is used when referring to the
average monthly rainfall in India
• Data are represented by inappropriate graphs or
charts
For example, a pie chart is used to represent the
distances of the different planets from the Sun
OHT 7.4 a

Key Stage 3 National Strategy
Common difficulties in handling
data 1 (ii)
• Graphs and charts are incorrectly drawn or
labelled
For example, the bars in a bar chart representing the
votes cast for candidates in a school election are
joined together or are of different widths
• Graphs and charts are read incorrectly or
interpreted inappropriately
For example, the vertical scale marked in thousands
on a population graph is misread: 350 000 is read as
350
OHT 7.4 b
© Crown copyright 2001
Key Stage 3 National Strategy
Common difficulties in handling
data 2
• Activities are aimless or contexts inappropriate
For example, vast quantities of data are collected
without any consideration of the purpose of the
enquiry
• Undue time is spent on mechanical skills and
there is insufficient emphasis on interpreting data
and making inferences
For example, pupils are taught to draw pie charts or
calculate a mean without understanding of when it is
appropriate to use these or how to interpret them
