### Shape

Child’s world is 3-d but 3-d shapes (polyhedra) are defined by their 2-d characteristics

• Representations of 2-d shapes (polygons) only true if drawn or shadows.
3-d shapes

Reception cube pyramid sphere cone

Year 6 dodecahedron

Independent Study Task
• Read Askew, M. and Wiliam, D (1995) ‘Careful choice of examples improves children’s concept formation’ in Askew, M. and , Wiliam, D. Recent research in mathematics education 5-16 London: HMSO
• Devise a set of at least 20 shape playing cards. Outline an activity that could be undertaken in the classroom to support children’s understanding of either right angles or polygons using your set of 20 cards. (P- Task design)
• Read Fujita, T. and Jones, K. (2007) ‘Learners Understanding of the Definitions and Hierarchical Classification of Quadrilaterals: Towards a Theoretical Framing’. Research in Mathematics Education, 9 (1), 3-20

What are the key points from their research?

What are the implications for teaching and learning?
