Pictorial representations
make use of diagrams, infographics and models to enable pupils to visualise core mathematical concepts easily and effectively.
Abstract representations
provide pupils with the opportunity to familiarise themselves with using mathematical symbols and to relate the use of
these symbols with the concrete and pictorial representations they previously encountered.
Pupils are also equipped with skills to construct their own mathematical expressions.
