This case study was conducted in Maasin,
Iloilo, the Philippines, to ascertain the weavers’ way of
life, particularly the mathematical concepts embodied in
their weaving practices. This study documented
mathematics concepts and competencies included in the K
to 12 Mathematics curriculum the weavers exhibited. A
holistic multiple case study design with a single unit of
analysis was employed in this study. Participant
observations and in-depth interviews were used with the
three purposively chosen informants. The researcher
utilized field notes, observation guides, recorded videos,
photographs, and artifacts for triangulation and analysis.
The mathematics concepts revealed from the weavers are
basic arithmetic, estimation, dimension, perimeter and
circumference, patterns, congruence, parallelism,
perpendicularity, geometric figures, and polygons. The
weavers manifest mathematical content standards on key
concepts and skills involving numbers, Four
Fundamental Operations, Non-standard and standard
measures of length and mass, the idea of perimeter and
circumference, the concept of measurement, continuous
patterns, lines, and symmetrical designs, parallel and
perpendicular lines, and quadrilaterals, and polygons,
circles, and solid figures. Recommendations on
embedding weaving activities in mathematics instruction
were discussed.
