Standard 8.PR.2 - Practice evaluating variable expressions with whole numbers.
Included Skills: Algebra
Model and solve problems using linear equations of the form: • ax = b • x/a = b, a ≠ 0 • ax + b = c • x/a + b = c, a ≠ 0 • a(x + b) = c concretely, pictorially and symbolically, where a, b and c are integers. • Achievement Indicators - Model a given problem with a linear equation and solve the equation using concrete models, e.g., counters, integer tiles. - Verify the solution to a given linear equation using a variety of methods, including concrete materials, diagrams and substitution. - Draw a visual representation of the steps used to solve a given linear equation and record each step symbolically. - Solve a given linear equation symbolically. - Identify and correct an error in a given incorrect solution of a linear equation. - Apply the distributive property to solve a given linear equation, e.g., 2(x + 3) = 5; 2 x + 6 = 5; ... - Solve a given problem using a linear equation and record the process.
