Measurement is valuable as an integrating skill throughout the curriculum and in everyday life. The use of estimation is vital in determining the reasonableness of measurement. Use measurement tools and units appropriately and recognize limitations in the precision of the measurement tools. Derive and use formulas for area, surface area, and volume of many types of figures. Using generalizations, compare the formula for the area of an n-sided, regular polygon to the formula for the area of a circle.
Relationships are central to mathematical understanding.
A study of patterns often reveals regularity, indicating the presence of a mathematical relationship. Studying relationships allows students to make generalizations and predictions about phenomena and occurrences. Create a graph to represent a real-life situation and draw inferences from it. Translate and solve a real-life problem using symbolic language. Identify a variety of situations explained by the same type of function.
