An angle with a measure less than 90°. Acute angle
Time displayed on a timepiece having hour and minute hands. Analog time
The measure, in square units, of the inside of a plane figure. Area
A rectangular arrangement of objects in equal rows or columns. Array
A group of items. Placing these items in a different order does not create a new combination. Combination
A solid figure that has a circular base and one vertex. Cone
Having the same size and shape.Congruent angles have the same measure.Congruent segments have the same length. Congruent
A rectangular solid having six congruent square faces. Cube
A three-dimensional figure with two circular bases, which are parallel and congruent. Cylinder
The line segment where two faces of a solid figure meet. Edge
Having the same value. Equivalent
A variable, or any combination of numbers, variables, and symbols that represents a mathematical relationship (e.g., 24 x 2 + 5 or 4a – 9). Expression
A plane figure that serves as one side of a solid figure. Face
A set of related addition and subtraction, or multiplication and division equations using the same numbers (e.g., 6+9=15, 15-9=6, 9+6=15, 15-6=9). Fact family
A whole number that divides evenly into another whole number (e.g., 1, 3, 5, and 15 are factors of 15). Factor
A relation in which every input value has a unique output value. Function
A polygon with 6 sides. Hexagon
A mathematical sentence that contains a symbol that shows the terms on either side of the symbol are unequal (e.g., 3+4>6). Inequality
A straight path extending in both directions with no endpoints. Line
A line that divides a figure into two halves that are mirror images of each other. Line of symmetry
A part of a line with two endpoints. Line segment
The number found by dividing the sum of a set of numbers by the number of addends. Mean (average)
The middle number in an ordered set of data, or the average of the two middle numbers when the set has two middle numbers. Median
The number(s) that occurs most often in a set of data. Mode
The product of a given whole number and another whole number (e.g., multiples of 4 are 4, 8, 12, 16….). Multiples
An equation or inequality with numbers. Number sentence
An angle with a measure more than 90º. Obtuse angle
A polygon with 8 sides. Octagon
A pair of numbers used to locate a point on a coordinate grid. The first number tells how far to move horizontally, and the second number tells how far to move vertically. Ordered pair
Lines that never intersect and are always the same distance apart. Parallel lines
A quadrilateral whose opposite sides are parallel and congruent. Parallelogram
A polygon with 5 sides. Pentagon
The distance around a figure. Perimeter
Two lines, segments or rays that intersect to form right angles. Perpendicular lines
A graph that uses pictures to show and compare information. Pictograph
A solid figure with a polygon base and triangular sides that meet at a single point (vertex). Pyramid
A polygon with 4 sides. Quadrilateral
A part of a line that has one endpoint and continues without end in one direction. Ray
A solid figure in which all six faces are rectangles. Rectangular prism
A transformation that produces the mirror image of a figure. Reflection (flip)
A parallelogram with four equal sides. Rhombus
An angle that measures exactly 90º. Right angle
A triangle that has a 90º angle. Right triangle
A movement of a figure that turns that figure around a fixed point. Rotation (turn)
A solid figure that has all points the same distance from the center. Sphere
A table that uses tally marks to record data. Tally chart
A movement of a figure to a new position without turning or flipping it. Translation (slide)
A quadrilateral with exactly one pair of parallel sides. Trapezoid
A point where lines, rays, sides of a polygon or edges of a polyhedron meet (corner). Vertex
The amount of space (in cubic units) that a solid figure can hold. Volume (capacity)
A statement that two mathematical expressions are equal. Equation
