Key Issue 1: What is
oral and mental
mathemtics
Primary Curriculum 2014…The principal focus of mathematics teaching in key stage 1 is to ensure that pupils develop confidence and mental fluency with whole numbers, counting and place value.
The principal focus of mathematics teaching in lower key stage 2 is to ensure that pupils become increasingly fluent with whole numbers and the four operations, including number facts and the concept of place value. This should ensure that pupils develop efficient written and mental methods and perform calculations accurately with increasingly large whole numbers.
Year 5/6…At this stage, pupils should develop their ability to solve a wider range of problems, including increasingly complex properties of numbers and arithmetic, and problems demanding efficient written and mentalmethods of calculation.
Mental Mathematics?

Calculations that are done in a student's head without the
guidance of pencil and paper, calculators or other aids.
