Mental Maths and Chandos Primary School

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

This means that children must be able to rapidly recall number facts, including number bonds, times tables as well as square numbers and factors.

In addition to the daily maths lesson (which normally lasts one hour) teachers deliver a 10-minute mental maths lesson.

This includes chanting tables, playing online and board games, in addition to other resources.

Half-termly ‘mental maths champion’ assemblies celebrate children’s mental maths ability.

Each year group has one mental maths target taken from their year group’s expectations. Children who achieve this target will receive a certificate in the Summer term.

All children have been allocated maths games which link to their year group specific target using Abacus.

Each child has been given a unique log-in by their teacher which allows them to access online games, as well as ‘Rewards Area’ where children can spend the virtual coins which they earn through successfully completing maths and grammar games.
