Number Words
In short: Math vocabulary for numbers: 35 terms on integers, fractions, decimals, exponents, square roots, and real numbers, each defined simply with a numeric example so every problem statement is easy to read.
Numbers come in many kinds, and this page lists the math vocabulary for numbers that sorts them out: whole number, integer, rational, irrational, prime, factor, multiple, exponent, square root, scientific notation. Each term has a short definition and a numeric example that shows what belongs in the group and what does not.
It is useful when a problem asks you to “classify each number” or to “write in lowest terms,” and you want to be sure of the vocabulary first. Print it for a unit review, or keep it beside a worksheet to verify the difference between a factor and a multiple before you answer. Grade levels are marked on each entry.
35 words on this page, each with a definition, a figure, a solved example and two quick questions.
