ab: Summary: In this action research, first-graders were challenged to cope
with a sequence of modelling tasks involving an analysis of given
situations and choices of mathematical tools. In the course of the
sequence, they underwent a change in the nature of their
problem-solving processes and developed modelling competencies.
Moreover, during the task sequence, the first-graders spontaneously
discovered the power of organizing problem data in a table. They did
not merely use their existing mathematical knowledge, but also
‘reinvented’ tables as a new mathematical tool. This paper
describes the gradual development of this tool as the children moved
along the task sequence. Notably, the first-graders exhibited this
progress in spite of having relatively little mathematical knowledge.
