Introduction to: The focus and demands of the new curriculum

The Aims of The New Curriculum

The National Curriculum for mathematics aims to ensure all pupils:

become fluent in the fundamentals of mathematics so that they are efficient in using and selecting the appropriate written algorithms and mental methods, underpinned by mathematical concepts

can solve problems by applying their mathematics to a variety of problems with increasing sophistication, including in unfamiliar contexts and to model real-life scenarios

can reason mathematically by following a line of enquiry and develop and present a justification, argument or proof using mathematical language.

2

The focus and demands of the new curriculum

The new National Curriculum is likely to have • An increased focus on arithmetic proficiency• A greater emphasis on learning number facts• Higher expectations in fractions, decimals and percentages• Less emphasis on data handling

3

Mathematical Proficiency

• Mathematical proficiency requires a focus on core knowledge and procedural fluency so that pupils can carry out mathematical procedures flexibly, accurately, consistently, efficiently, and appropriately. Procedures and understanding are developed in tandem.

4

Arithmetic Proficiency: achieving fluency in calculating with understanding

... an appreciation of number and number operations, which enables mental calculations and written procedures to be performed efficiently, fluently and accurately.

Developing conceptual understanding

The teacher’s job is to organise and provide the sorts of experiences which enable pupils to construct and develop their own understanding of mathematics, rather than simply communicate the ways in which they themselves understand the subject.(1989 National Curriculum, Non- Statutory Guidance, page C2)

Is this how teachers see their role?

Ofsted: Made to Measure“Schools should:

• tackle in-school inconsistency of teaching• increase the emphasis on problem solving across the

mathematics curriculum • develop the expertise of staff:

• in choosing teaching approaches and activities that foster pupils’ deeper understanding,

• in checking and probing pupils’ understanding during the lesson,

• in understanding the progression in strands of mathematics over time, so that they know the key knowledge and skills that underpin each stage of learning

• ensuring policies and guidance are backed up by professional development for staff “

What aspects of conceptual understanding and procedural fluency are required for each of these calculations?

Improving children’s Arithmetic Proficiency

Findings from Ofsted 2011:• Practical, hands-on experiences of using, comparing and

calculating with numbers and quantities … are of crucial importance in establishing the best mathematical start …

• Understanding of place value, fluency in mental methods, and good recall of number facts … are considered by the schools to be essential precursors for learning traditional vertical algorithms (methods)

• Subtraction is generally introduced alongside its inverse operation, addition, and division alongside its inverse, multiplication

• High-quality teaching secures pupils’ understanding of structure and relationships in number …

11

Other findings:• Skills in calculation are strengthened through solving

a wide range of problems.• Schools recognised the importance of moving

towards more efficient methods• Schools in the good practice survey had clear,

coherent calculation policies• Schools recognise the importance of good subject

knowledge and subject-specific teaching skills and seek to enhance these aspects of subject expertise.

What can we learn from other countries?

Problem solving, reasoning and procedural fluency’

“...there is a wider consensus amongst mathematics educators that conceptual understanding, procedural and factual fluency and the ability to apply knowledge to solve problems are all important and mutually reinforce each other.”

Singapore mathematics framework

Procedural fluency and conceptual understanding

• Singapore Maths does not rely on rote learning of facts and procedures without the underlying understanding required to use them effectively. The Ministry of Education (2006) explicitly states: “Although students should become competent in the various mathematical skills, over-emphasising procedural skills without understanding the underlying mathematical principles should be avoided”;

• Improving pupils’ attitudes is likely to raise achievement – links between success, confidence, enjoyment;

• High expectations;• Concrete, pictorial, abstract (CPA);• Visual problem solving strategies;• Focus on number and calculation from the beginning.

Towards written algorithms: Addition and subtraction

“Dependence on facts and procedures alone cannot ensure competence with arithmetic at the required level; competence also depends on identifying, understanding and acting on the underlying relations, equating and estimating quantities.”
