Eleven Plus Maths (11 Plus Maths) is one of the four disciplines of exam papers used in the selection process (11 plus exams) for entrance into Grammar Schools. Mathematics is also one of the papers used in common entrance exams when applying to many of the country's Independent Schools.

Unlike Verbal Reasoning, 11 Plus Maths does not tend to have set question types that tend to appear year after year. The 11+ Maths papers are more varied in their question style, however the same key topics or areas tend to be tested. These topics are predominantly the same as Key Stage 2 Maths (KS2 Maths) covered in school, however they do also introduce a few of the Key Stage 3 (KS3) Maths topics such as basic algebra.
