James says: "This is glossary of terms for UK KS3 Maths,[ages 11-13] taken Works quite well with a 'random glossary entry' html block on a main course page since the definitions are in a small font size.

PlanIn geometry, a two-dimensional diagram of a three-dimensional object, usually the view from directly above. | |
PlaneA flat surface. A line segment joining any two points in the surface will also lie in the surface. | |
PlotThe process of marking points. Points are usually defined by co-ordinates and plotted with reference to a given coordinate system. Noun - a collection of these points on a graph. | |
PointAn element, in geometry, that has position but no magnitude, for example a corner (vertex). | |
PolyhedronA 3D closed solid figure bounded by surfaces (faces) that are polygonal. Its faces meet in line segments called its edges. Its edges meet at points called vertices. For a polyhedron to be convex, it must lie completely to one side of a plane containing any face. If it is not convex it is concave. A regular polyhedron has identical regular polygons forming its faces and equal angles formed by its surfaces and edges. Example: a cube. Plural: polyhedra. | |
Positive NumberAny number greater than zero. Where a point on a line is labelled 0 and equally spaced points to one side of it are labelled +1, +2, +3 etc., these, and the numbers represented by decimal points between them, are positive numbers and are read ’positive one, positive two, positive three’ etc. | |
Pound (mass)Symbol: lb. An imperial unit of mass. In the imperial system, 14 lb = 1 stone. 1 lb is approximately 455 grams. 1 kilogram is approximately 2.2 lb. | |
Prime FactorThe factors of a number that are prime. Example: 2 and 3 are the prime factors of 12 (12 = 2 x 2 x 3). See also 'factor'. | |
Prime FactorisationThe process of expressing a number as the product of factors that are prime numbers. Example: 24 = 2 x 2 × 2 × 3 or 23 × 3 | |
