A discussion of numeracy (the ability to cope confidently with the mathematical demands of everyday life), focuses on provision of numeracy instruction alongside English-as-a-Second-Language (ESL) instruction for learners with low literacy skills. It looks first at considerations and methods for assessing student numeracy needs, including the nature of adult learning, student preferences and abilities, and differences in the uses of mathematical symbols and forms of computation in the learners' native language and culture. The discussion then turns to the attitudes and approaches to numeracy of ESL and literacy instructors, who may not be familiar with or comfortable with mathematics or mathematics teaching and may see mathematics skills as discrete and separate from literacy rather than as integral to it. Recommendations for training to teach adult mathematical literacy, based on recent initiatives, are offered. Specific classroom techniques for effective lesson planning and presentation are also outlined. Two numeracy activities, one introducing a place-value chart and one on metric measurement, are offered as illustrations of effective techniques.
