Abstract
This paper examines teacher actions that support young children to consider repeating pattens as co-variational (functional) relationships, to use this understanding to predict uncountable steps in the relationships, to express these relationships in general terms, and use repeating patterns to introduce proportional thinking. A teaching experiment was conducted in two classrooms, comprising of a total of 45 children whose average age was 9 years and 6 months. This experiment focused on exploring teacher actions (including the use of concrete materials, recording of data, and questions asked) that supported young children?s development of co-variational reasoning. The results indicated that explicit instruction assisted children to find patterns across the table as well as down the table, to find the relationships between the number of tiles and an uncountable number of repeats. Also the results indicate that young children are capable of not only thinking about the relationship between two data sets, but also of expressing this relationship in a very abstract form.
