Numeracy is the knowledge, skills, behaviours and dispositions that students need in order to use mathematics in a wide range of situations. It involves recognising and understanding the role of mathematics in the world and having the dispositions and capacities to use mathematical knowledge and skills purposefully.
Numeracy, like literacy, is key for students to access and make sense of their world. Being able to quantify and measure their environment in different ways will help them to make wiser judgements about the kind of actions to take in their lives. Our confidence and ability with numbers and its language impacts us financially, socially, and professionally.
How do we improve numeracy?
Numeracy can be defined as a proficiency, which involves confidence and competence with numbers and measures. It requires an understanding of the number system, a repertoire of computational skills and an inclination and ability to solve number problems in a variety of contexts. Numeracy also demands practical understanding of the ways in which information is gathered by counting and measuring, and is presented or represented in graphs, diagrams, charts and tables.
Numeracy includes:
understanding the number concept and number system (ones, tens, hundreds, thousands)
understanding and using mathematical symbols; being able to compare numbers
mastering basic number operations
(addition, subtraction, multiplication, division)
measurement (time, distance, area, weight, volume etc.)
money
geometry
reading and explaining data, graphs, diagrams, charts
logical reasoning
mental arithmetic
estimation and rounding
fractions, decimal fractions and percentages
These areas and skills relate to the whole curriculum and can be practiced across all subjects and used in a range of contexts and situations. In the same way that being able to read is essential, being numerate is crucial to life in this digital age.
Numeracy involves using mathematical ideas effectively to participate in daily life and make sense of the world. It incorporates the use of numerical, spatial, graphical, statistical and algebraic concepts and skills in a variety of contexts and involves the critical evaluation, interpretation, application and communication of mathematical information in a range of practical situations (NSW Numeracy K-12 Policy, 2007).
Numeracy is incorporated in the NSW Syllabuses for the Australian curriculum as a general capability alongside other learning across the curriculum areas.
