Ignore?
Number
A mathematical object used to count, label, and measure
Even
Can be divided exactly by 2
Odd
Cannot be divided exactly by 2
Prime Number
Only has factors of (can be divided evenly by) 1 or itself
Composite Number
Has factors of (can be divided evenly by) numbers other than 1 or itself.
Fractions
Fractions can describe something that is EITHER Part of a whole or Part of a set
Numerator
How many parts or objects there are
Denominator
How many objects there are in total (or parts there should be)
Proper Fractions
A proper fraction is a fraction where the numerator (the top number) is less than the denominator (the bottom number)
Improper fractions
An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number).
Mixed Fractions
A mixed fraction is a whole number and a fraction combined into one "mixed" number.
Simplify/Reduce
The process of changing an improper fraction to a mixed number OR changing a proper fraction to the lowest denominator

Sum
The result of joining two things together
Subtraction
The actions of splitting or seperating some things
Difference
The result of splitting or seperating some things
Multiplication
Product
Division
Repeated subtraction
Quotient
The result of repeated subtraction
Surface Area
the total area of the surface of an object
Slant Height
the distance from a point on the perimeter of the base of a cone to the apex of the cone; the distance from the midpoint of the base of one triangular face of a regular pyramid to the apex of the pyramid height: centre of base to apex
Volume
the amount of space occupied by an object
Dimensions
measurements such as length, width, and height
Right Angle
a 90° angle
Base
the side of a polygon or the face of an object from which the height is measured
Perimeter
the distance around a closed shape
Circumference
the distance around a circle, also the perimeter of the circle
Pyramid
A solid object where: The base is a polygon (a straight-sided flat shape) The sides are triangles which meet at the top (the apex).
Cone
an object with one circular base and one vertex; the line through the vertex and the centre of the base is perpendicular to the base
Lateral Area
the surface area of an object, not including the area of its bases
Sphere
an object where every point on the surface of the object is the same distance from the centre of the object. Example: A ball
Cylinder
A solid object with: two identical flat ends that are circular or elliptical and one curved side.
Hemisphere
half a sphere
(plural, radii): the distance or line segment from the centre of a circle to any point on the circle.
Diameter
the distance across a circle, measured through its centre; or the line segment that joins two points on the circle and passes through its centre
Composite

Cubic
units that measure volume
Regular
A shape whose faces are all equal
Length
The longer measurement
Width
The shorter measurement
Horizontal
Going side-to-side, like the horizon. Parallel to the horizon.
Vertical
