Fractions can describe something that is EITHER Part of a whole or Part of a set
How many parts or objects there are
How many objects there are in total (or parts there should be)
A proper fraction is a fraction where the numerator (the top number) is less than the denominator (the bottom number)
An improper fraction is a fraction where the numerator (the top number) is greater than or equal to the denominator (the bottom number).
A mixed fraction is a whole number and a fraction combined into one "mixed" number.
The process of changing an improper fraction to a mixed number OR changing a proper fraction to the lowest denominator

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
the amount of space occupied by an object
measurements such as length, width, and height
a 90° angle
the side of a polygon or the face of an object from which the height is measured
the distance around a closed shape
the distance around a circle, also the perimeter of the circle
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).
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
the surface area of an object, not including the area of its bases
