Abstract
This paper provides case studies of the attempts of four young children (a high achieving first-grader, a high achieving kindergarten student and two low achieving fIrst-graders) to solve three tasks involving three-dimensional shapes and their two-dimensional representations. Detailed descriptions of students' solutions are provided; these highlight the appropriateness of challenging geometric tasks for young students. High achieving students spontaneously made more frequent use of formal geometric terms when explaining their actions.
