Abstract(s)
This paper is part of the Project “Adaptive thinking and flexible computation: Critical issues”. It discusses what
is meant by adaptive thinking and presents the results of individual interviews with four pupils. The main goal
of the study is to understand pupils’ reasoning when solving numerical tasks involving additive situations,
and identify features associated with adaptive thinking. The results show that, in the case of first grade pupils,
the semantic aspects of the problem are involved in its resolution and the pupils’ performance appears to be
related to the development of number sense. The 2nd grade pupils seem to see the quantitative difference as
an invariant numerical relationship.
