RI.M:F&A:4. NECAP - Grade Level Expectation: Functions and Algebra.
M:F&A:4:3. Demonstrates conceptual understanding of algebraic expressions by using letters or symbols to represent unknown quantities to write simple linear algebraic expressions involving any one of the four operations; or by evaluating simple linear algebraic expressions using whole numbers. (State)
M:F&A:4:4. Demonstrates conceptual understanding of equality by showing equivalence between two expressions using models or different representations of the expressions, by simplifying numerical expressions where left to right computations may be modified only by the use of parentheses (expressions consistent with the parameters of M(F&A)-4-3), and by solving one-step linear equations of the form ax = c, x +/- b = c, where a, b, and c are whole numbers with a not equal to 0.
