Abstract

Ordering is an important activity for cognitive development of a child and it has a fruitful form in the idea of (finite) sequence. A schematic representation of concrete sequences (of numbers or letters) is used to foster the idea of function. Leading pupils to discover simple laws of correspondence and to compose the expressions which formulate them seems to be the first possible instance of such activities feasible in elementary school practice.

Keywords: Sequences, discovering of rules, finding sums.
