The benefits of supporting young children to engage in early algebra are well established within the research literature (Blanton et al., 2015; Kieran, 2022). Patterning is a recognized pathway into functional thinking and often a focus of curriculum in the first years of formal schooling. However, studies (e.g., Rittle-Johnson et al., 2015) have found that young children can succeed in more sophisticated patterning than they are normally encouraged to do at home or school. Other research in the functional thinking field (e.g., Blanton et al., 2015) has also found that young students can seek and express recursive, covariational and functional relationships at more sophisticated levels than previously thought. Collectively, the field shows that young children are more capable in patterning and functional thinking than many curricula require. Given that many children in their first years of schooling are introduced to algebra through repeating patterns, in this presentation, we focus on student identification of functional relationships in repeating patterns.
