ROCHA, Maria Isabel  y  MENINO, Hugo Alexandre. Development of number sense in multiplication: A case study with children of 7/8 years old. Relime [online]. 2009, vol.12, n.1, pp.103-134. ISSN 2007-6819.

This article discusses the sense of number in multiplication based on a case study, under the auspices of the project "Developing the sense of number: Perspectives and curricular demands", carried out in Portugal with children between five and twelve years of age. The approach used was quantitative and interpretive in nature and took the form of a case study. The analysis centers on the strategies used by second grade children (7 or 8 years old) to solve multiplication problems included in a series of classroom tasks. The results show that the contexts of the tasks, situated in the rectangular model, facilitate comprehension of multiplication, its properties and numeric multiplicative relationships.
