C.4.4. Use simple two-dimensional coordinate systems to find locations on maps and to represent points and simple figures.

WI.D. Measurement: Students in Wisconsin will select and use appropriate tools (including technology) and techniques to measure things to a specified degree of accuracy. They will use measurements in problem-solving situations.

D.4.1. Recognize and describe measurable attributes, such as length, liquid capacity, time, weight (mass), temperature, volume, monetary value, and angle size, and identify the appropriate units to measure them.

D.4.2. Demonstrate understanding of basic facts, principles, and techniques of measurement, including appropriate use of arbitrary and standard units (metric and US Customary); appropriate use and conversion of units within a system (such as yards, feet, and inches; kilograms and grams; gallons, quarts, pints, and cups); judging the reasonableness of an obtained measurement as it relates to prior experience and familiar benchmarks.

D.4.3. Read and interpret measuring instruments (e.g., rulers, clocks, thermometers).

D.4.4. Determine measurements directly by using standard tools to these suggested degrees of accuracy length to the nearest half-inch or nearest cm; weight (mass) to the nearest ounce or nearest 5 grams; temperature to the nearest 5; time to the nearest minute; monetary value to dollars and cents; liquid capacity to the nearest fluid ounce.

D.4.5. Determine measurements by using basic relationships (such as perimeter and area) and approximate measurements by using estimation techniques.

WI.E. Statistics and Probability: Students in Wisconsin will use data collection and analysis, statistics and probability in problem-solving situations, employing technology where appropriate.

E.4.1. Work with data in the context of real-world situations by formulating questions that lead to data collection and analysis; determining what data to collect and when and how to collect them; collecting, organizing, and displaying data; drawing reasonable conclusions based on data.

E.4.2. Describe a set of data using high and low values, and range; most frequent value (mode); middle value of a set of ordered data (median).

E.4.3. In problem-solving situations, read, extract, and use information presented in graphs, tables, or charts.

E.4.4. Determine if future events are more, less, or equally likely, impossible, or certain to occur.

E.4.5. Predict outcomes of future events and test predictions using data from a variety of sources.

In the context of real-world problem situations, the student will use algebraic techniques to define and describe the problem to determine and justify appropriate solutions.
