Unpacked Content
Knowledge
Students know:
- Interpretations of parts of algebraic expressions such as terms, factors, and coefficients.
Skills
Students are able to:
- Produce mathematical expressions that model given contexts.
- Provide a context that a given mathematical expression accurately fits.
- Explain the reasoning for selecting a particular algebraic expression by connecting the quantities in the expression to the physical situation that produced them.
Understanding
Students understand that:
- Physical situations can be represented by algebraic expressions which combine numbers from the context, variables representing unknown quantities, and operations indicated by the context.
- Different, but equivalent, algebraic expressions can be formed by approaching the context from a different perspective.
