Skills - a statement of what a student should be able to do with that knowledge upon leaving high school. Rationale - an explanation for educators, parents, and citizens about why it is essential for students to understand that standard, and how their lives and the lives of others improve with this understanding. This analysis also makes people aware of the consequences of their actions for themselves and others, and leads to a heightened sense of responsibility and accountability . Benchmarks identify building blocks underlying the principles embedded in the standard and consist of assumptions, intermediate conclusions and elaborations for each standard. People make choices because they can't have everything they want.
Economic wants are desires that can be satisfied by consuming a good, service, or leisure activity.
Goods are objects that can satisfy people's wants. Services are actions that can satisfy people's wants. People's choices about what goods and services to buy and consume determine how resources will be allocated. Whenever a choice is made, something is given up. The opportunity cost of a choice is the value of the best alternative given up.
