Term	Definition
Integer	Set of whole numbers and their opposites. No fractions or decimals. Includes: • the counting numbers {1, 2, 3, ...}, • zero {0}, • and the negative of the counting numbers {-1, -2, -3, ...}
Whole number	Zero and positive numbers with no fractional or decimal part. {0,1,2,3,4,5...}
Opposite Numbers	Numbers that have the same magnitude but are on opposite sides of zero on the number line Opposites have the same absolute value.
Absolute Value	The distance a number is from zero on the number line.
Number Line	A line on which numbers are marked at intervals, used to illustrate simple numerical operations. A number line can be horizontal or vertical.
Origin	Zero on a number line.
Horizontal	In a side-to-side direction.
Vertical	In an up-down direction or position. Upright. Example: trees grow in a vertical direction.
Sum	The answer to an addition problem.
Difference	The answer to a subtraction problem.
Product	The answer to a multiplication problem.
Quotient	The answer to a division problem.
Positive	A magnitude or value greater than zero.
Negative	A magnitude or value less than zero.
Zero Pair	A number together with its opposite result in zero.
Magnitude	Value, size
Additive Inverse	What you add to a number to get zero. The negative of a number.
Coordinate Plane	The plane containing a horizontal number line, the "x" axis and a vertical number line, the "y" axis.
Coordinates	A set of values that show an exact position. On graphs it is usually a pair of numbers: the first number shows the distance along, and the second number shows the distance up or down.
Ordered Pair	A pair of numbers used to show the position on a graph, where the "x" (horizontal) value is first, and the "y" (vertical) value is second. Usually written in parentheses like this: (12,5)
Quadrant	Any of the 4 areas made when we divide up a plane by an x and y axis. They are usually numbered I, II, III and IV
Circumference	The distance around a circle.
Diameter	Any line segment from one point on a circle going through the center of the circle to another point on the circle.
Chord	Any line segment starting from one point on a circle to another point on the circle.
Radius	Any line segment from the center of a circle to a point on the circle.
Symmetry	When two or more parts are identical after a flip, slide or turn.
Congruent	Figures that are the same shape and size
Similar	Figures that are the same shape but not necessarily the same size.
Triangle	A 3-sided polygon with straight sides.
Polygon	A closed plane figure formed by three or more line segments meeting at points called vertices.
Quadrilateral	A polygon with 4 sides, 4 vertices and 4 angles.
Parallelogram	A quadrilateral with 2 pairs of congruent parallel sides
Acute angle	An angle that is less than 90 degrees.
Obtuse Angle	An angle that is more than 90 degrees.
Right Angle	An angle that measures exactly 90 degrees.
Isosceles Triangle	A triangle with two congruent sides and angles.
Equilateral Triangle	A triangle with all three congruent sides and angles.
Scalene Triangle	A triangle with no congruent sides or angles.
Regular Polygon	A polygon with all interior angles and all sides congruent.
Ratio	A comparison of two or more quantities. Can be written as a:b, a to b, or a/b.
Fraction Bar	The line that separates the numerator and the denominator in a fraction. It indicates division.
Improper Fraction	A fraction whose numerator is greater than or equal to the denominator.
Mixed Number	A number that contains a whole number and a fraction.
Reciprocal	A flipped version of the number or fraction. In other words, 1 divided by that number. When we multiply a number by its reciprocal we get 1. Ex: 3/4 and 4/3 are reciprocals
Inverse	Opposite. The inverse of adding 9 is subtracting 9. The inverse of multiplying by 5 is dividing by 5
Inverse Property of Addition	The sum of a number and its negative (the "additive inverse") is always zero. a + (−a) =
Inverse Property of Multiplication	Multiplying a number by its reciprocal (the "multiplicative inverse") is always one. a × (1/a) = 1
Balance	When both sides have the same quantity.
