Content Standard: Students in Wisconsin will use numbers effectively for various purposes, such as counting, measuring, estimating, and problem solving.
Rationale
People use numbers to quantify, describe, and label things in
the world around them. It is important to know the many uses of
numbers and various ways of representing them. Number sense is
a matter of necessity, not only in one's occupation but also in
the conduct of daily life, such as shopping, cooking, planning
a budget, or analyzing information reported in the media. When
computing, an educated person needs to know which operations (e.g.,
addition, multiplication), which procedures (e.g., mental techniques,
algorithms*), or which technological aids (e.g., calculator, spreadsheet)
are appropriate.
