Maths Vocabulary

"The national curriculum for mathematics reflects the importance of spoken language in pupils’ development across the whole curriculum – cognitively, socially and linguistically. The quality and variety of language that pupils hear and speak are key factors in developing their mathematical vocabulary and presenting a mathematical justification, argument or proof. They must be assisted in making their thinking clear to themselves as well as others, and teachers should ensure that pupils build secure foundations by using discussion to probe and remedy their misconceptions."

National Curriculum in England, Department for Education, 2013


Using correct mathematical language is crucial for thinking, learning and communicating mathematically. Children should be introduced to the appropriate vocabulary at a time when it is relevant and required. Find vocabulary lists below for each area of maths for each year group.
