Big Ideas in Number: Developing a Robust Understanding for P-2

2 Day Program – Over 3 months

back to Programs

A robust understanding of critical number concepts is crucial to ensure all students have access to the F – 10 Mathematics curriculum. Two of these fundamental concepts are defined as Trusting the Count and Place Value. These form the first two of the ‘Big Ideas in Number’, and students would be expected to deeply understand these ‘big ideas’ before the end of Year 2.

Professor Di Siemon, an acknowledged national expert in the development of children’s Number development will be presenting two full day, spaced workshops that focus on research informed and evidence-based practices that build both teacher capacity and student understanding in these ‘big ideas’.

The workshops will focus on practices that support a child’s development of these ‘big ideas’ through the use of experiential activities that enable oral literacy, enhance reasoning and build on the most current research into Number. This PL is funded through the Learning in Families Together (LIFT) initiative.

Through involvement in these workshops teachers will:

  • Build an understanding of the research behind the big ideas of Trusting the Count and Place Value
  • Become proficient in using assessment tools developed through research, to inform future teaching
  • Build curricula knowledge in mathematics and understand the progression of learning in relation to this aspect of Number
  • Increase their pedagogical content knowledge through the use of research-informed and evidence-based practices
