Interpreting the Parts of an Expression or Equation: Sample Algebra 1 EOC Questions

Students read an expression the way a reader reads a sentence: naming its terms, factors, coefficients, and constants, and explaining what each one means in a real-world situation. Part of the skill is seeing a chunk such as (1 + r) as one single entity rather than three symbols.

How the Algebra 1 EOC tests this benchmark

The expression or equation is always given, and the EOC never asks students to rewrite it or produce an equivalent, which is what separates this benchmark from the exponent and polynomial ones. Items are heavily context based: what does the 45 in a cost equation represent, which factor gives the growth per year. Multiple choice and drop-down items are the usual formats.
