2Some questions
- What is meant by numeracy in the 21st century?
- What repertoire of numeracy practices do young
people demonstrate in life outside school? - How can we develop numeracy practices at school?
3What is numeracy?
- Numeracy involves
- A numerate person can
- A numerate person knows
- A numerate person is
4What is numeracy?
- Some lay views of numeracy
- numbers (doing sums, arithmetic)
- the basic maths people need in order to survive
in the real world - the name for primary school maths
- the name for the vegie maths subject in secondary
school
5Early definitions of numeracy
- The mirror image of literacy, but involving
quantitative thinking. - Crowther Report, 1959 (UK)
6Early definitions of numeracy
- Possessing an at homeness with numbers and an
ability to use mathematical skills to cope
confidently with the practical demands of
everyday life, together with understanding of
information presented in mathematical terms. - Cockcroft Report, 1982 (UK)

8Mathematical literacy
- Mathematical literacy is the capacity to
identify, understand and engage in mathematics,
and to make well-founded judgments about the role
that mathematics plays in an individuals current
and future private life, occupational life,
social life with peers and relatives, and life as
a constructive, concerned and reflective citizen. - PISA, 2001
9Distinguishing numeracy from mathematics
- Mathematics climbs the ladder of abstraction to
see, from sufficient height, common patterns in
seemingly different things. Abstraction is what
gives mathematics its power it is what enables
methods derived from one context to be applied in
others. But abstraction is not the focus of
numeracy. Instead, numeracy clings to specifics,
marshalling all relevant aspects of setting and
context to reach conclusions. - Steen, 2001
1020th century numeracy
- To be numerate is to use mathematics effectively
to meet the general demands of life at home, in
paid work, and for participation in community and
civic life. - Numeracy, A Priority for All
- (DETYA, 2000)

19Calculating crosswind using a watch face
- Angle is 45º 45 minutes is three quarters
around the watch face so the crosswind component
is about three quarters of the 20 knot wind
speed, namely 15 knots.

38Exploiting tools for numeracy
- Claim
- Technology robs learners of the ability to
think. - Counter claim
- Technology can change and enhance the way humans
solve problems.
39Technology as Master
40Technology as Servant
41Technology as Partner
- My calculator has become my best friend. His
name is Wilbur. Me and Wilbur go on fantastical
adventures together through Maths land. I dont
know what Id do without him.
42Technology as Extension of Self
- My calculator is practically a part of myself.
Its like my third brain. I use it whenever it
can help me do anything faster.
43Calculators in Primary Mathematics project
- 6 Melbourne schools 1000 children 80 teachers
- Prep-Year 4
- Children given their own arithmetic calculators
- Teachers not provided with activities or program
44Technology as a numeracy tool
45Technology as partner
Underground numbers!
46Exploiting contexts for numeracy
- Connections to real life
- Connections to other school subjects

available to start work immediately - Want to work, actively looking for work,
available to start work within 4 weeks - Want to work, actively looking for work, not
available to start work within 4 weeks - Want to work, not actively looking because they
believe they wouldnt be able to find a job, but
would be able to start within 4 weeks - Want to work but not actively looking and not
available to start within 4 weeks - Dont want to work
- Permanently unable to work

- Is Barbie a realistic representation of human
proportions? - What would Barbie look like if scaled up to human
height?
55Numeracy messages
- Numeracy has no content of its own - it inherits
its content from the context. - Workers do use mathematics but not necessarily
the standard, visible mathematics taught at
school. - Technology is ubiquitous in the world outside
school and should be exploited intelligently to
develop students numeracy practices.
