2. Operating on number

2. Operating on number

Theme 2 is Operating on number. It comprises two interconnected core concepts, each of which covers a set of ‘knowledge, skills and understanding’ statements.

For each core concept, we have produced a detailed guidance document underpinned by a clear set of pedagogical principles and practices to support planning. Each document offers an overview of the content within the statements of knowledge, skills and understanding, and breaks them down further into focused key ideas.

At the end of the documents, some of the key ideas are exemplified, to demonstrate what planning for secure and deep understanding of mathematics at Key Stage 3 might involve. Other key ideas are left for individual departments and teachers to work on, alongside existing material and schemes.

There is also a guidance document that offers an overview of the theme as a whole.

  • 2 Operating on number
    Theme 2 is about students understanding the structures underpinning calculation using each of the four operations. It includes the solving of equations, which is essentially concerned with operations on, as yet, unknown numbers
     
  • 2.1 Arithmetic procedures
    This core concept offers guidance on developing a strong understanding of the mathematical structures that underpin the standard procedures for calculation with decimals, fractions and directed numbers
     
  • 2.2 Solving linear equations
    This core concept explores how linear equations are effectively the formulation of a series of operations on unknown numbers and how the solving of such equations is concerned with undoing these operations to find the value of the unknown
