Resumo(s)
3D decomposition is considered a spatial reasoning process (Davis et al., 2015). Spatial
structuring is a form of abstraction that creates mental models of shapes’ structures (Battista
& Clements, 1996). Since early grades, both play an important role in understanding shapes’
structures and in learning how to manipulate them flexibly and fluently. 3D shapes have a
strong presence in early grades, yet there is still little research about the way students learn
their structures. We seek to answer the following questions: How do 1st graders decompose
3D shapes? How are these decompositions related to spatial structuring?
