This book presents examples of numeracy applications developed in a wide range of courses in a Further Education college in Wales. The numeracy case studies are not limited to simple arithmetic and tasks involving shape and space, but include more advanced topics such as: statistical analysis, mathematical modelling, calculus and design of algorithms. A broad definition of numeracy is adopted by the authors, in line with the range of numeracy skills expected and valued by employers. In addition to a knowledge of mathematical techniques, numeracy is considered to include: problem solving, especially in the design of solutions to non-routine tasks; communication of mathematical results in formats which are suitable for the intended audience and facilitate decision making; an ability to use computer technology to collect and process data; and a familiarity with number which allows appropriate levels of accuracy to be chosen, estimates made and errors detected.
