Discuss BrunerBruner (1966) suggests an important model for depicting levels or modes of representation. One can experience and subsequently think about a particular idea or concept on three different levels: enactive, iconic and symbolic. These ideas have been extended by Lesh (1979) and are discussed in the next section. At the Bruner enactive level, learning involves hands-on or direct experience. The strength of enactive learning is its sense of immediacy. The mode of learning Bruner terms iconic is based on the use of the visual medium: films, pictures, diagrams, and the like. Symbolic learning is that stage in which one uses abstract symbols to represent reality. (Post article)For example, consider the operation "two plus three." From the child's perspective this idea is experienced enactively if the child joins a set of two objects with a set of three objects and determines that there are five objects altogether. This same notion is experienced iconically if the child views a series of pictures. The first might have two objects (birds, children), which are joined with a set of three objects in a second picture. The third picture might show that here are five altogether. Note that at the iconic level the determination of the result, five, is actually made by the developer of the diagram or photo, not by the child. The relationship is symbolically encountered when the child writes 2 + 3 = 5. Bruner contends that all three types of interpretations or modes are important and that there is a common sense order implied by three levels because each requires familiarity with the earlier modes of representation.Implicit in his and later work (Lesh, 1979) is the fact that these modes should be interactive in nature, the child freely moving from one mode to another. For example, given the equation 2 + 3 = 5, the child could be asked to draw a picture of this situation. This would in effect be a translation from the symbolic (2 + 3 = 5) to the iconic mode (pictures).Your representation of 5. Was it enactive, iconic or symbolic – or a combination> How do the resources fit in to this? Which use symbolic only? Which use enactive? A combination of more than one mode? How could you represent in that way. Think about this when you look at the next problems.Bruner and Skemp and two names that we will refer to in most sessions and are key to our beliefs around primary mathematics teaching.

Relational and Instrumental Understanding
• Relational understanding is….”what I have always meant by
understanding: knowing both what to do and why.”
• “Instrumental understanding I would have until recently not
have regarded as understanding at all. It is what I have in the
past described as ‘rules without reasons’ without realising
that for many pupils and their teachers the possession of such
a rule, and the ability to use it, was what they meant by

The new National Curriculum: Aims
The national curriculum for mathematics aims to ensure that all pupils:
• become fluent in the fundamentals of mathematics, including through
varied and frequent practice with increasingly complex problems over
time, so that pupils develop conceptual understanding and the ability to
recall and apply knowledge rapidly and accurately
• reason mathematically by following a line of
enquiry, conjecturing relationships and generalisations, and developing an
argument, justification or proof using mathematical language
• can solve problems by applying their mathematics to a variety of
routine and non-routine problems with increasing sophistication, including
breaking down problems into a series of simpler steps and persevering in
Catering for the needs of all pupils….
The expectation is that the majority of pupils will move
through the programmes of study at broadly the
same pace. However, decisions about when to progress
should always be based on the security of pupils
understanding and their readiness to progress to the
next stage. Pupils who grasp concepts rapidly should be
challenged through being offered rich and sophisticated
problems before any acceleration through new content.
Those who are not sufficiently fluent with earlier
material should consolidate their understanding,
including through additional practice, before moving

Information and communication
Calculators should not be used as a
substitute for good written and mental
arithmetic. They should therefore only
be introduced near the end of key stage
2 to support pupils’ conceptual
understanding and exploration of more
complex number problems, if written
and mental arithmetic are secure. In
both primary and secondary schools,
teachers should use their judgement
about when ICT tools should be used.

Key principles in supporting the development of
written calculation methods
• Mental calculation confidence should be established before
written methods are introduced
• Mental calculation strategies need to be specifically taught
• We need to carefully structure progression into written
methods to ensure each new method builds on
• Children need to be encouraged to make decisions about
which method to use and when
• Opportunities to apply and problem solve with calculation
skills and strategies should run alongside practice of them
• We need to ensure that we use resources to support
understanding of how methods represent number
