Year 4 domain plan Number - Addition and subtraction Mental fluency Addition and subtraction Pupils should be taught to: add and subtract numbers mentally including; a three digit number and ones, a three digit number and tens; a three digit number and hundreds (Year 3) Rehearse methods identified on the school calculation policy for Year 4 Number and place value link find 1000 more or less than a given number Written fluency Addition and subtraction Pupils should be taught to: add and subtract numbers with up to 4 digits using the formal written methods of columnar addition and subtraction where appropriate As identified by the school’s calculation policy Estimate, use inverse and check Addition and subtraction Pupils should be taught to: estimate and use inverse operations to check answers to a calculation Solve problems Addition and subtraction Pupils should be taught to: solve addition and subtraction two-step problems in contexts, deciding which operations and methods to use and why Statements 1 Term 2 √ √ 3 Rehearse mental methods identified by calculation policy add and subtract numbers mentally including; a three digit number and ones, a three digit number and tens; a three digit number and hundreds (Year 3 – 3C1) round any number to the nearest 10, 100 or 1000 (number and place value – 4N4b) add and subtract numbers with up to 4 digits using the formal written methods of columnar addition and subtraction where appropriate 4C2 estimate and use inverse operations to check answers to a calculation 4C3 solve addition and subtraction two-step problems in contexts, deciding which operations and methods to use and why 4C4 √ √ √ √ √ √ √ √ Notes and guidance (non-statutory) Pupils continue to practise both mental methods and columnar addition and subtraction with increasingly large numbers to aid fluency (see Mathematics Appendix 1). © Herts for Learning 2014 √ Herts for Learning – Teaching and Learning Herts for Learning – Teaching and Learning Number and place value link round any number to the nearest 10, 100 or 1000
