Summary: In this action research, firstgraders 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 problemsolving processes and developed modelling competencies. Moreover, during the task sequence, the firstgraders 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 firstgraders exhibited this progress in spite of having relatively little mathematical knowledge.
