Abstract(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?
