Grade 8 - Patterns and Relations

Standard 8.PR.2 - Practice solving two step linear equations.

Included Skills:

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.

Students who have achieved this outcome should be able to:
A. Model a given problem with a linear equation and solve the equation using concrete models, e.g., counters, integer tiles.
B. Verify the solution to a given linear equation using a variety of methods, including concrete materials, diagrams and substitution.
C. Draw a visual representation of the steps used to solve a given linear equation and record each step symbolically.
D. Solve a given linear equation symbolically.
E. Identify and correct an error in a given incorrect solution of a linear equation.
F. Apply the distributive property to solve a given linear equation, e.g., 2(x + 3) = 8 becomes 2x + 6 = 8
G. Solve a given problem using a linear equation and record the process.
