These workbooks are part of a Mexican series of instructional materials designed for Spanish speaking adults who are in the process of becoming literate or have recently become literate in their native language. The workbooks, divided in two volumes, are designed to teach skills required in managing ordinary financial transactions and daily tasks requiring a knowledge of weights and measures. Topics covered include different methods of counting; daily situations requiring a knowledge of math; instruments of measurement, such as a scale, a clock, a pitcher, and a measuring tape; real life situations involving computations; multiplication; census figures; distances; division; numerical comparisons; use of decimals; and measurement of terrain.
