Understanding the Big Ideas of Arithmetic

19 May
2 June
23 June



10:00 – 14:30



The DfE accredited textbooks and the White Rose mathematics planning are widely used by schools. The NCETM CPD materials for teachers are now available to support their understanding of each year group’s curriculum from the perspective of teaching for mastery so this course will support teachers to understand the 4 big principles of arithmetic that underpin these schemes of learning: property of number, unitising, multiplicative reasoning and equivalence.

Who is this for?

This Work Group will support teachers and subject leaders in Key Stage 1 and/or 2.

Dates, times and venue

Dates and times:

19 May 2020- 10:00am to 14:30pm

2 June 2020- 10:00am to 14:30pm

All sessions will be held at:

Rye Community Primary School | Aquinas Trust, The Grove, Rye, East Sussex, TN31 7ND

Between sessions, teachers will be asked to explore the outcomes of some of the ideas discussed in the sessions with their own classes, or with a group of children.

Intended Outcomes

By the end of the Work Group participating teachers will:

  • understand how the big ideas of arithmetic underpin commonly used schemes of learning.
  • recognise the big ideas of arithmetic in calculating strategies
  • be able to use the big ideas of arithmetic to identify pupils’ difficulties and misconceptions
  • know how the big ideas of arithmetic are experienced through multiple representations.

By the end of the Work Group pupils of participating teachers will:

  • have experienced elements of the big ideas of arithmetic to make connections across the whole arithmetic curriculum
  • begin to learn from core representations used to develop understanding of the big ideas of arithmetic
  • will have experienced a problem solving approach to learning

Expectations of participants and their schools

Participants will be expected to:

  • Attend all three sessions.
  • To try out one or two tasks/ideas in his/ her own school.

Who is leading the Work Group?
