Relational thinking and operating on unknown quantities. A study with 5 to 10 years old children

Abstract : The following research design combines relational thinking as an aspect of algebraic thinking with the understanding of variables. In clinical interviews, 5 to 10 years old children were confronted with tasks that required the description of relations between known and unknown quantities. Their answers were examined regarding the ways in which relations are described and thereby variables are seen.
