What is mathematical literacy?

Mathematical literacy is the ability to use numbers, measures, shapes and data to understand and solve real problems and interpret results.

Everyday contexts

Calculating a discount, checking the scale of a graph or estimating travel time requires mathematical thinking. Correct calculation matters, but one must first model what the question asks and check whether an answer is plausible. If a graph axis does not start at zero, a difference can look larger than it is. Mathematical literacy is more than memorising formulas; it includes justification.

Developing it

Secure basic number and operation knowledge, then practise explaining and solving problems in varied settings. Teachers can show worked examples and invite students to explain methods in speech or diagrams. Using everyday situations does not mean abandoning conceptual accuracy. OECD’s learning framework connects knowledge, skills and purposeful action in new contexts.
