This session showcases a teaching sequence that aims to help students build connection between quadratics and parabolas. A variety of teaching tasks are implemented to address graphics features of parabolas (such as symmetry property), as well as their relationship with algebraic manipulation of quadratic functions (such as finding axis of symmetry, or x-coordinate of turning point). A range of carefully designed assessment items are experimented to assess students' understanding of the concepts beyond procedure work. Some findings from students' work will be shared and discussed. Close analysis of these tasks will be presented to evaluate students' learning and to inform future teaching. Details from the Australian Curriculum 9.0 will be highlighted and examined.
