CALCULATION POLICY
ADDITION AND SUBTRACTION

 

The Effective Maths calculation policy for addition and subtraction provides an overview of the content and methods taught in each year group from Year 1 to Year 6. For Years 1-4 it also includes the visual representations of the methods. (In Year 5 and 6 there are no new methods and the representations encountered are the same as in earlier years. What is different is the range of number that children work with.)

​

 

For each year group in Years 1-4 the document provides:

(i) a content summary section;

(ii) details about the approaches used for teaching the above;

(iii) the representations used.

(For Year 5 and 6 the document contains (i) and (ii).)

​

 

The content summary sections (i) and the details about the approaches used sections (ii) include content from:

  • addition and subtraction units 1 and 2;

  • the Block 3 calculation unit;

  • money and decimals units;

  • fractions unit 2 (Years 3-6).

 

 

The representations sections do not include the representations used in money/decimals units or fractions units. (These representations are essentially the same as those used in the main addition and subtraction units.)

 

 

The document is provided in several versions:

  • whole school version;

  • year group specific versions;

  • a Key Stage 1 only version (for infant schools).

​

 

For Years 1-4 there are two versions of each year group specific version:

  • a landscape version, like a PowerPoint slide, containing (i), (ii) and (iii);

  • a portrait version of the representations section (iii) with notes to support the representations.
