Furthermore, according to Baroody (1998), there is little evidence of the need for logical training for developing the
concept of number, however, there is evidence showing that counting experiences are directly related to the
understanding of number sense. In this line, Bermejo (1990), among others, favours a comprehensive approach due
to the necessary complementarity between the teaching of logic operations and numerical skills, considering that
both are indispensable skills that develop the complex cognitive processes, allowing a greater understanding of
number.
