Maths Terms for 11-13 Yr Olds
Note: You may download the entries for this glossary here. If you wish to use this in your own Moodle course, first make a blank glossary and then follow the instructions for importing glossary entries here.
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.

GraphA diagram showing a relationship between variables. Adjective: graphical. A graph showing information that isn't continuous is often called a 'chart' instead. | |
InequalityStatements such as b > c are inequalities. They differ from equations in that they don't have equals signs and don't have fixed solutions, only boundary solutions. For example in the above it is known that b must be at least greater than c, but how much greater is not known. Boundary solutions to inequalities can be indicated graphically using shading. | |
InterceptThe value of the non-zero coordinate of the point where a line on a graph cuts an axis. The y intercept is given the symbol c in straight line graphs of the form y = mx + c. | |
LinearIn algebra, an adjective describing an expression, equation or relationship of degree one. Example: 2x + 3y = 7 is a linear equation. This linear equation with its two variables, x and y, can be represented as a straight line graph. The relationship between x and y is linear. | |
NotationAny convention for recording mathematical ideas in writing and symbols. Example: Money is recorded using decimal notation e.g. £2.50. | |
OriginA fixed point from which measurements are taken. See also Cartesian co-ordinate system. On a graph the origin is normally given by the point at which the x axis meets the y axis, at the co-ordinate (0,0). | |
PatternA systematic arrangement of numbers, shapes, values or other objects according to a rule. | |
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. | |
ProofA chain of reasoning that establishes the truth of a proposition. | |
