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.
