Maths findings

The following key findings, taken together, reflect the ‘what’ and ‘how’ that underpin effective learning through which pupils become fluent in calculating, solving problems and reasoning about number. „ Practical, hands-on experiences of using, comparing and calculating with numbers and quantities and the development of mental methods are of crucial importance in establishing the best mathematical start in the Early Years Foundation Stage and Key Stage 1. The schools visited couple this with plenty of opportunities for developing mathematical language so that pupils learn to express their thinking using the correct vocabulary. „ Understanding of place value, fluency in mental methods, and good recall of number facts such as multiplication tables and number bonds are considered by the schools to be essential precursors for learning traditional vertical algorithms (methods) for addition, subtraction, multiplication and division.3 „ Subtraction is generally introduced alongside its inverse operation, addition, and division alongside its inverse, multiplication. Pupils’ fluency and understanding of this concept of inverse operations are aided by practice in rewriting ‘number sentences’ like 3 + 5 = 8 as 8 – 3 = 5 and 8 – 5 = 3 and solving ‘missing number’ questions like – 4 = 5 by thinking 5 + 4 = 9 or 9 – 4 = 5. „ High-quality teaching secures pupils’ understanding of structure and relationships in number, for instance place value and the effect of multiplying or dividing by 10, and progress in developing increasingly sophisticated mental and written methods. „ In lessons and in interviews with inspectors, pupils often chose the traditional algorithms over other methods. When encouraged, most showed flexibility in their thinking and approaches, enabling them to solve a variety of problems as well as calculate accurately. „ Pupils’ confidence, fluency and versatility are nurtured through a strong emphasis on problem solving as an integral part of learning within each topic. Skills in calculation are strengthened through solving a wide range of problems, exploiting links with work on measures and data handling, and meaningful application to cross-curricular themes and work in other subjects. „ The schools are quick to recognise and intervene in a focused way when pupils encounter difficulties. This ensures misconceptions do not impede the next steps in learning. „ Many of the schools have reduced the use of ‘expanded methods’ and ‘chunking’ in moving towards efficient methods because they find that too many steps in methods confuse pupils, especially the less able.
