Mathematics Vocabulary

The national curriculum for mathematics reflects the importance of spoken language in pupils’ development across the whole curriculum. 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. At Lammack, we promote the use of correct mathematical vocabulary in discussions.

This vocabulary list of 142 words and phrases details the words and definitions that children need to know and use by the end of Key Stage 2. It is adapted from the ‘Ultimate Maths Vocabulary List’ from Third Space Learning.
