Grade 8 - Patterns and Relations

Standard 8.PR.2 - Practice evaluating multi variable expressions.

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.

• 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.
