Develop, test and explain real number concepts. Construct and apply mathematical rules and algorithms to solve problems. Select and use appropriate units, tools and techniques to measure to the degree of precision and accuracy desired in particular situations. Develop physical references for commonly used measures. Describe, estimate and use measures of length, perimeter, weight, time, temperature, money and capacity.
Measure quantities indirectly using algebra, geometry or trigonometry.
Develop and use formulas and procedures to solve problems involving measurements. Formulate hypotheses, design and conduct experiments using appropriate technology, draw conclusions based on data and communicate results. Use experimental and theoretical probability to represent and solve problems. Analyze data to determine strength of relationships between sets, draw conclusions and make predictions. Recognize and use patterns, functions and algebraic operations to solve problems.
