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.
