FAST Math Grade 6 key terms

A number expressible as a ratio of integers with a nonzero denominator, represented by whole numbers, fractions or suitable decimal forms.

The distance of a number from zero on a number line, distinguished from its signed value in an ordered comparison.

The largest positive whole-number divisor shared by the stated numbers, distinct from the least positive multiple they share.

The multiplicative inverse of a nonzero quantity, used in valid division transformations rather than as a reason to invert arbitrary fractions.

A power notation describing repeated multiplication for positive integer cases, with additional defined rules and conditions for zero or negative integers.

A comparison of quantities in the named order, requiring a distinction between part-to-part and part-to-whole relationships in context.

A quantity per one unit of another quantity, retaining both units so that its interpretation is not accidentally inverted.

A symbol representing a quantity whose role and permitted values should be identified before writing or interpreting an expression or equation.

A numerical factor multiplying a variable part in an algebraic term, distinguished from an exponent and from a separate constant term.

A value or set of values satisfying the original equation or inequality, checked by substitution and any relevant domain restrictions.

A distance measured at right angles to a chosen base, not automatically the visible slanted side in an area problem.

The total area of the relevant exterior faces of a solid, measured in square units rather than the cubic units of volume.

A measure of three-dimensional space, whose formula and units must match the actual solid and stated dimensions in the problem.

A numerical component of an ordered location, whose axis, sign and position must be identified rather than reversed by visual guesswork.

A ratio of corresponding lengths in similar figures, whose effect on area differs from its direct effect on a length.

The entire group about which a statistical question seeks information, distinguished from the particular observations actually selected for a sample.

A systematic effect of the sampling method that over-represents or omits relevant groups and is not automatically removed by a large count.

The central ordered data position or mean of two central values, requiring sorting and correct handling of the number of observations.

The difference between the maximum and minimum observed values, distinguished from the number of categories or the average of the data.

The proportion of observed trials producing a particular outcome, which can differ from a theoretical probability in a limited sample.
